VAR-201708-0212 CVE-2015-7692 NTP Input validation vulnerability CVSS V2: 5.0
CVSS V3: 7.5
Severity: HIGH
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash). NOTE: This vulnerability exists due to an incomplete fix for CVE-2014-9750. NTP Contains an input validation vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. NTP is prone to a denial-of-service vulnerability. A remote attacker may exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Due to the nature of this issue, code-injection may be possible; however this has not been confirmed. Versions prior to NTP 4.2.8p4 and 4.3.x prior to 4.3.77 are vulnerable. Note #2: This issue was previously titled 'NTP CVE-2015-7692 Denial of Service Vulnerability'. The title has been changed to better reflect the vulnerability information. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201607-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: NTP: Multiple vulnerabilities Date: July 20, 2016 Bugs: #563774, #572452, #581528, #584954 ID: 201607-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in NTP, the worst of which could lead to Denial of Service.

Description: The Network Time Protocol (NTP) is used to synchronize a computer's time with another referenced time source. These packages include the ntpd service which continuously adjusts system time and utilities used to query and configure the ntpd service. Security Fix(es): * It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntp_crypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. (CVE-2015-7691, CVE-2015-7692, CVE-2015-7702) * A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory. (CVE-2015-7701) * An off-by-one flaw, leading to a buffer overflow, was found in cookedprint functionality of ntpq. (CVE-2015-7852) * A NULL pointer dereference flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. (CVE-2015-7977) * A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. (CVE-2015-7978) * It was found that when NTP was configured in broadcast mode, a remote attacker could broadcast packets with bad authentication to all clients. The clients, upon receiving the malformed packets, would break the association with the broadcast server, causing them to become out of sync over a longer period of time. (CVE-2015-7979) * It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. (CVE-2015-5194) * It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) was referenced by the statistics or filegen configuration command. (CVE-2015-5195) * It was found that NTP's :config command could be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals). (CVE-2015-5196, CVE-2015-7703) * It was discovered that the sntp utility could become unresponsive due to being caught in an infinite loop when processing a crafted NTP packet. (CVE-2015-5219) * A flaw was found in the way NTP verified trusted keys during symmetric key authentication. An authenticated client (A) could use this flaw to modify a packet sent between a server (B) and a client (C) using a key that is different from the one known to the client (A). (CVE-2015-7974) * A flaw was found in the way the ntpq client processed certain incoming packets in a loop in the getresponse() function. A remote attacker could potentially use this flaw to crash an ntpq client instance. (CVE-2015-8158) The CVE-2015-5219 and CVE-2015-7703 issues were discovered by Miroslav LichvA!r (Red Hat).

CVE-2015-5300 It was found that ntpd did not correctly implement the -g option: Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. ntpd could actually step the clock multiple times by more than the panic threshold if its clock discipline doesn't have enough time to reach the sync state and stay there for at least one update. If a man-in-the-middle attacker can control the NTP traffic since ntpd was started (or maybe up to 15-30 minutes after that), they can prevent the client from reaching the sync state and force it to step its clock by any amount any number of times, which can be used by attackers to expire certificates, etc. This is contrary to what the documentation says. Normally, the assumption is that an MITM attacker can step the clock more than the panic threshold only once when ntpd starts and to make a larger adjustment the attacker has to divide it into multiple smaller steps, each taking 15 minutes, which is slow. For example: ntpq -c ':config pidfile /tmp/ntp.pid' ntpq -c ':config driftfile /tmp/ntp.drift' In Debian ntpd is configured to drop root privileges, which limits the impact of this issue. CVE-2015-7704 If ntpd as an NTP client receives a Kiss-of-Death (KoD) packet from the server to reduce its polling rate, it doesn't check if the originate timestamp in the reply matches the transmit timestamp from its request. An off-path attacker can send a crafted KoD packet to the client, which will increase the client's polling interval to a large value and effectively disable synchronization with the server. CVE-2015-7850 An exploitable denial of service vulnerability exists in the remote configuration functionality of the Network Time Protocol. A specially crafted configuration file could cause an endless loop resulting in a denial of service. An attacker could provide a the malicious configuration file to trigger this vulnerability. CVE-2015-7855 It was found that NTP's decodenetnum() would abort with an assertion failure when processing a mode 6 or mode 7 packet containing an unusually long data value where a network address was expected. CVE-2015-7871 An error handling logic error exists within ntpd that manifests due to improper error condition handling associated with certain crypto-NAK packets. An unauthenticated, off-path attacker can force ntpd processes on targeted servers to peer with time sources of the attacker's choosing by transmitting symmetric active crypto-NAK packets to ntpd. This attack bypasses the authentication typically required to establish a peer association and allows an attacker to make arbitrary changes to system time. For the oldstable distribution (wheezy), these problems have been fixed in version 1:4.2.6.p5+dfsg-2+deb7u6. For the stable distribution (jessie), these problems have been fixed in version 1:4.2.6.p5+dfsg-7+deb8u1. For the testing distribution (stretch), these problems have been fixed in version 1:4.2.8p4+dfsg-3. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.8p4+dfsg-3. We recommend that you upgrade your ntp packages. Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/ntp-4.2.8p4-i486-1_slack14.1.txz: Upgraded.

VAR-201708-0036 CVE-2015-7853 NTPĀ  Buffer Error Vulnerability CVSS V2: 7.5
CVSS V3: 9.8
Severity: CRITICAL
The datalen parameter in the refclock driver in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to execute arbitrary code or cause a denial of service (crash) via a negative input value. NTP Is vulnerable to a buffer error.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Pillow is a Python-based image processing library. There is currently no information about this vulnerability, please feel free to follow CNNVD or manufacturer announcements. Network Time Protocol is prone to a local buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. An attacker may exploit this issue to execute arbitrary code within the context of the application. Failed exploit attempts will likely cause denial-of-service conditions. Versions prior to NTP 4.2.8p4 and 4.3.x prior to 4.3.77 are vulnerable. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201607-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: NTP: Multiple vulnerabilities Date: July 20, 2016 Bugs: #563774, #572452, #581528, #584954 ID: 201607-15 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in NTP, the worst of which could lead to Denial of Service.

I. Background The ntpd(8) daemon is an implementation of the Network Time Protocol (NTP) used to synchronize the time of a computer system to a reference time source. II. Problem Description Crypto-NAK packets can be used to cause ntpd(8) to accept time from an unauthenticated ephemeral symmetric peer by bypassing the authentication required to mobilize peer associations. [CVE-2015-7871] FreeBSD 9.3 and 10.1 are not affected. If ntpd(8) is fed a crafted mode 6 or mode 7 packet containing an unusual long data value where a network address is expected, the decodenetnum() function will abort with an assertion failure instead of simply returning a failure condition. [CVE-2015-7855] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd(8) that may cause it to crash, with the hypothetical possibility of a small code injection. [CVE-2015-7854] A negative value for the datalen parameter will overflow a data buffer. NTF's ntpd(8) driver implementations always set this value to 0 and are therefore not vulnerable to this weakness. If you are running a custom refclock driver in ntpd(8) and that driver supplies a negative value for datalen (no custom driver of even minimal competence would do this) then ntpd would overflow a data buffer. It is even hypothetically possible in this case that instead of simply crashing ntpd the attacker could effect a code injection attack. [CVE-2015-7853] If an attacker can figure out the precise moment that ntpq(8) is listening for data and the port number it is listening on or if the attacker can provide a malicious instance ntpd(8) that victims will connect to then an attacker can send a set of crafted mode 6 response packets that, if received by ntpq(8), can cause ntpq(8) to crash. [CVE-2015-7852] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause ntpd(8) to overwrite files. [CVE-2015-7851]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that will cause it to crash and/or create a potentially huge log file. Specifically, the attacker could enable extended logging, point the key file at the log file, and cause what amounts to an infinite loop. [CVE-2015-7850]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause a crash or theoretically perform a code injection attack. [CVE-2015-7849]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to enable mode 7 packets, and if the use of mode 7 packets is not properly protected thru the use of the available mode 7 authentication and restriction mechanisms, and if the (possibly spoofed) source IP address is allowed to send mode 7 queries, then an attacker can send a crafted packet to ntpd that will cause it to crash. [CVE-2015-7848]. The default configuration of ntpd(8) within FreeBSD does not allow mode 7 packets. If ntpd(8) is configured to use autokey, then an attacker can send packets to ntpd that will, after several days of ongoing attack, cause it to run out of memory. [CVE-2015-7701]. The default configuration of ntpd(8) within FreeBSD does not use autokey. If ntpd(8) is configured to allow for remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password, it's possible for an attacker to use the "pidfile" or "driftfile" directives to potentially overwrite other files. [CVE-2015-5196]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration An ntpd(8) client that honors Kiss-of-Death responses will honor KoD messages that have been forged by an attacker, causing it to delay or stop querying its servers for time updates. Also, an attacker can forge packets that claim to be from the target and send them to servers often enough that a server that implements KoD rate limiting will send the target machine a KoD response to attempt to reduce the rate of incoming packets, or it may also trigger a firewall block at the server for packets from the target machine. For either of these attacks to succeed, the attacker must know what servers the target is communicating with. An attacker can be anywhere on the Internet and can frequently learn the identity of the target's time source by sending the target a time query. [CVE-2015-7704] The fix for CVE-2014-9750 was incomplete in that there were certain code paths where a packet with particular autokey operations that contained malicious data was not always being completely validated. Receipt of these packets can cause ntpd to crash. [CVE-2015-7702]. The default configuration of ntpd(8) within FreeBSD does not use autokey. III. Impact An attacker which can send NTP packets to ntpd(8), which uses cryptographic authentication of NTP data, may be able to inject malicious time data causing the system clock to be set incorrectly. [CVE-2015-7871] An attacker which can send NTP packets to ntpd(8), can block the communication of the daemon with time servers, causing the system clock not being synchronized. [CVE-2015-7704] An attacker which can send NTP packets to ntpd(8), can remotely crash the daemon, sending malicious data packet. [CVE-2015-7855] [CVE-2015-7854] [CVE-2015-7853] [CVE-2015-7852] [CVE-2015-7849] [CVE-2015-7848] An attacker which can send NTP packets to ntpd(8), can remotely trigger the daemon to overwrite its configuration files. [CVE-2015-7851] [CVE-2015-5196] IV. Workaround No workaround is available, but systems not running ntpd(8) are not affected. Network administrators are advised to implement BCP-38, which helps to reduce risk associated with the attacks. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. The ntpd service has to be restarted after the update. A reboot is recommended but not required. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install The ntpd service has to be restarted after the update. A reboot is recommended but not required. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility.

Corrected: 2015-10-26 11:35:40 UTC (stable/10, 10.2-STABLE) 2015-10-26 11:36:55 UTC (releng/10.2, 10.2-RELEASE-p6) 2015-10-26 11:37:31 UTC (releng/10.1, 10.1-RELEASE-p23) 2015-10-26 11:36:40 UTC (stable/9, 9.3-STABLE) 2015-10-26 11:42:25 UTC (releng/9.3, 9.3-RELEASE-p29) CVE Name: CVE-2015-7701, CVE-2015-7702, CVE-2015-7703, CVE-2015-7704, CVE-2015-7848, CVE-2015-7849, CVE-2015-7850, CVE-2015-7851, CVE-2015-7852, CVE-2015-7853, CVE-2015-7854, CVE-2015-7855, CVE-2015-7871 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit https://security.FreeBSD.org/. I. II. Problem Description Crypto-NAK packets can be used to cause ntpd(8) to accept time from an unauthenticated ephemeral symmetric peer by bypassing the authentication required to mobilize peer associations. [CVE-2015-7871] FreeBSD 9.3 and 10.1 are not affected. [CVE-2015-7855] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd(8) that may cause it to crash, with the hypothetical possibility of a small code injection. [CVE-2015-7854] A negative value for the datalen parameter will overflow a data buffer. NTF's ntpd(8) driver implementations always set this value to 0 and are therefore not vulnerable to this weakness. If you are running a custom refclock driver in ntpd(8) and that driver supplies a negative value for datalen (no custom driver of even minimal competence would do this) then ntpd would overflow a data buffer. It is even hypothetically possible in this case that instead of simply crashing ntpd the attacker could effect a code injection attack. [CVE-2015-7853] If an attacker can figure out the precise moment that ntpq(8) is listening for data and the port number it is listening on or if the attacker can provide a malicious instance ntpd(8) that victims will connect to then an attacker can send a set of crafted mode 6 response packets that, if received by ntpq(8), can cause ntpq(8) to crash. [CVE-2015-7852] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause ntpd(8) to overwrite files. [CVE-2015-7851]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that will cause it to crash and/or create a potentially huge log file. Specifically, the attacker could enable extended logging, point the key file at the log file, and cause what amounts to an infinite loop. [CVE-2015-7850]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause a crash or theoretically perform a code injection attack. [CVE-2015-7849]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to enable mode 7 packets, and if the use of mode 7 packets is not properly protected thru the use of the available mode 7 authentication and restriction mechanisms, and if the (possibly spoofed) source IP address is allowed to send mode 7 queries, then an attacker can send a crafted packet to ntpd that will cause it to crash. [CVE-2015-7848]. The default configuration of ntpd(8) within FreeBSD does not allow mode 7 packets. If ntpd(8) is configured to use autokey, then an attacker can send packets to ntpd that will, after several days of ongoing attack, cause it to run out of memory. [CVE-2015-7701]. The default configuration of ntpd(8) within FreeBSD does not use autokey. If ntpd(8) is configured to allow for remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password, it's possible for an attacker to use the "pidfile" or "driftfile" directives to potentially overwrite other files. [CVE-2015-5196]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration An ntpd(8) client that honors Kiss-of-Death responses will honor KoD messages that have been forged by an attacker, causing it to delay or stop querying its servers for time updates. Also, an attacker can forge packets that claim to be from the target and send them to servers often enough that a server that implements KoD rate limiting will send the target machine a KoD response to attempt to reduce the rate of incoming packets, or it may also trigger a firewall block at the server for packets from the target machine. For either of these attacks to succeed, the attacker must know what servers the target is communicating with. An attacker can be anywhere on the Internet and can frequently learn the identity of the target's time source by sending the target a time query. [CVE-2015-7704] The fix for CVE-2014-9750 was incomplete in that there were certain code paths where a packet with particular autokey operations that contained malicious data was not always being completely validated. Receipt of these packets can cause ntpd to crash. [CVE-2015-7702]. The default configuration of ntpd(8) within FreeBSD does not use autokey. III. Impact An attacker which can send NTP packets to ntpd(8), which uses cryptographic authentication of NTP data, may be able to inject malicious time data causing the system clock to be set incorrectly. [CVE-2015-7871] An attacker which can send NTP packets to ntpd(8), can block the communication of the daemon with time servers, causing the system clock not being synchronized. [CVE-2015-7704] An attacker which can send NTP packets to ntpd(8), can remotely crash the daemon, sending malicious data packet. [CVE-2015-7855] [CVE-2015-7854] [CVE-2015-7853] [CVE-2015-7852] [CVE-2015-7849] [CVE-2015-7848] An attacker which can send NTP packets to ntpd(8), can remotely trigger the daemon to overwrite its configuration files. [CVE-2015-7851] [CVE-2015-5196] IV. Workaround No workaround is available, but systems not running ntpd(8) are not affected. Network administrators are advised to implement BCP-38, which helps to reduce risk associated with the attacks. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. The ntpd service has to be restarted after the update. A reboot is recommended but not required. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install The ntpd service has to be restarted after the update. A reboot is recommended but not required. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. [FreeBSD 10.2] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-102.patch.bz2 # bunzip2 ntp-102.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-102.patch.asc # gpg --verify ntp-102.patch.asc [FreeBSD 10.1] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-101.patch.bz2 # bunzip2 ntp-101.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-101.patch.asc # gpg --verify ntp-101.patch.asc [FreeBSD 9.3] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-93.patch.bz2 # bunzip2 ntp-93.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-93.patch.asc # gpg --verify ntp-93.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # find contrib/ntp -type f -empty -delete c) Recompile the operating system using buildworld and installworld as described in https://www.FreeBSD.org/handbook/makeworld.html. d) For 9.3-RELEASE and 10.1-RELEASE an update to /etc/ntp.conf is recommended, which can be done with help of the mergemaster(8) tool on 9.3-RELEASE and with help of the etcupdate(8) tool on 10.1-RELEASE. Restart the ntpd(8) daemon, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch.

On October 21st, 2015, NTP.org released a security advisory detailing 13 issues regarding multiple DoS vulnerabilities, information disclosure vulnerabilities, and logic issues that may result in an attacker gaining the ability to modify an NTP server's advertised time. Workarounds that mitigate one or more of the vulnerabilities may be available for certain products, please see the individual Cisco Bug IDs for details. CVE-2015-5194 It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. CVE-2015-5195 It was found that ntpd exits with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) is referenced by the statistics or filegen configuration command CVE-2015-5219 It was discovered that sntp program would hang in an infinite loop when a crafted NTP packet was received, related to the conversion of the precision value in the packet to double. CVE-2015-5300 It was found that ntpd did not correctly implement the -g option: Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. ntpd could actually step the clock multiple times by more than the panic threshold if its clock discipline doesn't have enough time to reach the sync state and stay there for at least one update. If a man-in-the-middle attacker can control the NTP traffic since ntpd was started (or maybe up to 15-30 minutes after that), they can prevent the client from reaching the sync state and force it to step its clock by any amount any number of times, which can be used by attackers to expire certificates, etc. This is contrary to what the documentation says. Normally, the assumption is that an MITM attacker can step the clock more than the panic threshold only once when ntpd starts and to make a larger adjustment the attacker has to divide it into multiple smaller steps, each taking 15 minutes, which is slow. CVE-2015-7701 A memory leak flaw was found in ntpd's CRYPTO_ASSOC. CVE-2015-7703 Miroslav Lichvar of Red Hat found that the :config command can be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals). For example: ntpq -c ':config pidfile /tmp/ntp.pid' ntpq -c ':config driftfile /tmp/ntp.drift' In Debian ntpd is configured to drop root privileges, which limits the impact of this issue. CVE-2015-7704 If ntpd as an NTP client receives a Kiss-of-Death (KoD) packet from the server to reduce its polling rate, it doesn't check if the originate timestamp in the reply matches the transmit timestamp from its request. An off-path attacker can send a crafted KoD packet to the client, which will increase the client's polling interval to a large value and effectively disable synchronization with the server. A specially crafted configuration file could cause an endless loop resulting in a denial of service. CVE-2015-7852 A potential off by one vulnerability exists in the cookedprint functionality of ntpq. A specially crafted buffer could cause a buffer overflow potentially resulting in null byte being written out of bounds. CVE-2015-7871 An error handling logic error exists within ntpd that manifests due to improper error condition handling associated with certain crypto-NAK packets. An unauthenticated, off-path attacker can force ntpd processes on targeted servers to peer with time sources of the attacker's choosing by transmitting symmetric active crypto-NAK packets to ntpd. For the oldstable distribution (wheezy), these problems have been fixed in version 1:4.2.6.p5+dfsg-2+deb7u6. For the stable distribution (jessie), these problems have been fixed in version 1:4.2.6.p5+dfsg-7+deb8u1. For the testing distribution (stretch), these problems have been fixed in version 1:4.2.8p4+dfsg-3. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.8p4+dfsg-3. We recommend that you upgrade your ntp packages. Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/ntp-4.2.8p4-i486-1_slack14.1.txz: Upgraded.

Corrected: 2015-10-26 11:35:40 UTC (stable/10, 10.2-STABLE) 2015-10-26 11:36:55 UTC (releng/10.2, 10.2-RELEASE-p6) 2015-10-26 11:37:31 UTC (releng/10.1, 10.1-RELEASE-p23) 2015-10-26 11:36:40 UTC (stable/9, 9.3-STABLE) 2015-10-26 11:42:25 UTC (releng/9.3, 9.3-RELEASE-p29) CVE Name: CVE-2015-7701, CVE-2015-7702, CVE-2015-7703, CVE-2015-7704, CVE-2015-7848, CVE-2015-7849, CVE-2015-7850, CVE-2015-7851, CVE-2015-7852, CVE-2015-7853, CVE-2015-7854, CVE-2015-7855, CVE-2015-7871 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit https://security.FreeBSD.org/. I. II. Problem Description Crypto-NAK packets can be used to cause ntpd(8) to accept time from an unauthenticated ephemeral symmetric peer by bypassing the authentication required to mobilize peer associations. [CVE-2015-7871] FreeBSD 9.3 and 10.1 are not affected. If ntpd(8) is fed a crafted mode 6 or mode 7 packet containing an unusual long data value where a network address is expected, the decodenetnum() function will abort with an assertion failure instead of simply returning a failure condition. [CVE-2015-7855] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd(8) that may cause it to crash, with the hypothetical possibility of a small code injection. [CVE-2015-7854] A negative value for the datalen parameter will overflow a data buffer. NTF's ntpd(8) driver implementations always set this value to 0 and are therefore not vulnerable to this weakness. If you are running a custom refclock driver in ntpd(8) and that driver supplies a negative value for datalen (no custom driver of even minimal competence would do this) then ntpd would overflow a data buffer. It is even hypothetically possible in this case that instead of simply crashing ntpd the attacker could effect a code injection attack. [CVE-2015-7853] If an attacker can figure out the precise moment that ntpq(8) is listening for data and the port number it is listening on or if the attacker can provide a malicious instance ntpd(8) that victims will connect to then an attacker can send a set of crafted mode 6 response packets that, if received by ntpq(8), can cause ntpq(8) to crash. [CVE-2015-7852] If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause ntpd(8) to overwrite files. [CVE-2015-7851]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd(8) was configured to disable authentication, then an attacker can send a set of packets to ntpd that will cause it to crash and/or create a potentially huge log file. Specifically, the attacker could enable extended logging, point the key file at the log file, and cause what amounts to an infinite loop. [CVE-2015-7850]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to allow remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password or if ntpd was configured to disable authentication, then an attacker can send a set of packets to ntpd that may cause a crash or theoretically perform a code injection attack. [CVE-2015-7849]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration. If ntpd(8) is configured to enable mode 7 packets, and if the use of mode 7 packets is not properly protected thru the use of the available mode 7 authentication and restriction mechanisms, and if the (possibly spoofed) source IP address is allowed to send mode 7 queries, then an attacker can send a crafted packet to ntpd that will cause it to crash. [CVE-2015-7848]. The default configuration of ntpd(8) within FreeBSD does not allow mode 7 packets. If ntpd(8) is configured to use autokey, then an attacker can send packets to ntpd that will, after several days of ongoing attack, cause it to run out of memory. [CVE-2015-7701]. The default configuration of ntpd(8) within FreeBSD does not use autokey. If ntpd(8) is configured to allow for remote configuration, and if the (possibly spoofed) source IP address is allowed to send remote configuration requests, and if the attacker knows the remote configuration password, it's possible for an attacker to use the "pidfile" or "driftfile" directives to potentially overwrite other files. [CVE-2015-5196]. The default configuration of ntpd(8) within FreeBSD does not allow remote configuration An ntpd(8) client that honors Kiss-of-Death responses will honor KoD messages that have been forged by an attacker, causing it to delay or stop querying its servers for time updates. Also, an attacker can forge packets that claim to be from the target and send them to servers often enough that a server that implements KoD rate limiting will send the target machine a KoD response to attempt to reduce the rate of incoming packets, or it may also trigger a firewall block at the server for packets from the target machine. For either of these attacks to succeed, the attacker must know what servers the target is communicating with. An attacker can be anywhere on the Internet and can frequently learn the identity of the target's time source by sending the target a time query. [CVE-2015-7704] The fix for CVE-2014-9750 was incomplete in that there were certain code paths where a packet with particular autokey operations that contained malicious data was not always being completely validated. Receipt of these packets can cause ntpd to crash. [CVE-2015-7702]. The default configuration of ntpd(8) within FreeBSD does not use autokey. III. Impact An attacker which can send NTP packets to ntpd(8), which uses cryptographic authentication of NTP data, may be able to inject malicious time data causing the system clock to be set incorrectly. [CVE-2015-7871] An attacker which can send NTP packets to ntpd(8), can block the communication of the daemon with time servers, causing the system clock not being synchronized. [CVE-2015-7704] An attacker which can send NTP packets to ntpd(8), can remotely crash the daemon, sending malicious data packet. [CVE-2015-7855] [CVE-2015-7854] [CVE-2015-7853] [CVE-2015-7852] [CVE-2015-7849] [CVE-2015-7848] An attacker which can send NTP packets to ntpd(8), can remotely trigger the daemon to overwrite its configuration files. [CVE-2015-7851] [CVE-2015-5196] IV. Workaround No workaround is available, but systems not running ntpd(8) are not affected. Network administrators are advised to implement BCP-38, which helps to reduce risk associated with the attacks. V. Solution Perform one of the following: 1) Upgrade your vulnerable system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. The ntpd service has to be restarted after the update. A reboot is recommended but not required. 2) To update your vulnerable system via a binary patch: Systems running a RELEASE version of FreeBSD on the i386 or amd64 platforms can be updated via the freebsd-update(8) utility: # freebsd-update fetch # freebsd-update install The ntpd service has to be restarted after the update. A reboot is recommended but not required. 3) To update your vulnerable system via a source code patch: The following patches have been verified to apply to the applicable FreeBSD release branches. a) Download the relevant patch from the location below, and verify the detached PGP signature using your PGP utility. [FreeBSD 10.2] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-102.patch.bz2 # bunzip2 ntp-102.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-102.patch.asc # gpg --verify ntp-102.patch.asc [FreeBSD 10.1] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-101.patch.bz2 # bunzip2 ntp-101.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-101.patch.asc # gpg --verify ntp-101.patch.asc [FreeBSD 9.3] # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-93.patch.bz2 # bunzip2 ntp-93.patch.bz2 # fetch https://security.FreeBSD.org/patches/SA-15:25/ntp-93.patch.asc # gpg --verify ntp-93.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch # find contrib/ntp -type f -empty -delete c) Recompile the operating system using buildworld and installworld as described in https://www.FreeBSD.org/handbook/makeworld.html. d) For 9.3-RELEASE and 10.1-RELEASE an update to /etc/ntp.conf is recommended, which can be done with help of the mergemaster(8) tool on 9.3-RELEASE and with help of the etcupdate(8) tool on 10.1-RELEASE.

On October 21st, 2015, NTP.org released a security advisory detailing 13 issues regarding multiple DoS vulnerabilities, information disclosure vulnerabilities, and logic issues that may result in an attacker gaining the ability to modify an NTP server's advertised time. Workarounds that mitigate one or more of the vulnerabilities may be available for certain products, please see the individual Cisco Bug IDs for details. CVE-2015-5194 It was found that ntpd could crash due to an uninitialized variable when processing malformed logconfig configuration commands. CVE-2015-5195 It was found that ntpd exits with a segmentation fault when a statistics type that was not enabled during compilation (e.g. timingstats) is referenced by the statistics or filegen configuration command CVE-2015-5219 It was discovered that sntp program would hang in an infinite loop when a crafted NTP packet was received, related to the conversion of the precision value in the packet to double. CVE-2015-5300 It was found that ntpd did not correctly implement the -g option: Normally, ntpd exits with a message to the system log if the offset exceeds the panic threshold, which is 1000 s by default. This option allows the time to be set to any value without restriction; however, this can happen only once. If the threshold is exceeded after that, ntpd will exit with a message to the system log. This option can be used with the -q and -x options. ntpd could actually step the clock multiple times by more than the panic threshold if its clock discipline doesn't have enough time to reach the sync state and stay there for at least one update. If a man-in-the-middle attacker can control the NTP traffic since ntpd was started (or maybe up to 15-30 minutes after that), they can prevent the client from reaching the sync state and force it to step its clock by any amount any number of times, which can be used by attackers to expire certificates, etc. This is contrary to what the documentation says. Normally, the assumption is that an MITM attacker can step the clock more than the panic threshold only once when ntpd starts and to make a larger adjustment the attacker has to divide it into multiple smaller steps, each taking 15 minutes, which is slow. CVE-2015-7701 A memory leak flaw was found in ntpd's CRYPTO_ASSOC. CVE-2015-7703 Miroslav Lichvar of Red Hat found that the :config command can be used to set the pidfile and driftfile paths without any restrictions. A remote attacker could use this flaw to overwrite a file on the file system with a file containing the pid of the ntpd process (immediately) or the current estimated drift of the system clock (in hourly intervals). For example: ntpq -c ':config pidfile /tmp/ntp.pid' ntpq -c ':config driftfile /tmp/ntp.drift' In Debian ntpd is configured to drop root privileges, which limits the impact of this issue. CVE-2015-7704 If ntpd as an NTP client receives a Kiss-of-Death (KoD) packet from the server to reduce its polling rate, it doesn't check if the originate timestamp in the reply matches the transmit timestamp from its request. An off-path attacker can send a crafted KoD packet to the client, which will increase the client's polling interval to a large value and effectively disable synchronization with the server. A specially crafted configuration file could cause an endless loop resulting in a denial of service. CVE-2015-7852 A potential off by one vulnerability exists in the cookedprint functionality of ntpq. A specially crafted buffer could cause a buffer overflow potentially resulting in null byte being written out of bounds. CVE-2015-7871 An error handling logic error exists within ntpd that manifests due to improper error condition handling associated with certain crypto-NAK packets. An unauthenticated, off-path attacker can force ntpd processes on targeted servers to peer with time sources of the attacker's choosing by transmitting symmetric active crypto-NAK packets to ntpd. For the oldstable distribution (wheezy), these problems have been fixed in version 1:4.2.6.p5+dfsg-2+deb7u6. For the stable distribution (jessie), these problems have been fixed in version 1:4.2.6.p5+dfsg-7+deb8u1. For the testing distribution (stretch), these problems have been fixed in version 1:4.2.8p4+dfsg-3. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.8p4+dfsg-3. We recommend that you upgrade your ntp packages. Here are the details from the Slackware 14.1 ChangeLog: +--------------------------+ patches/packages/ntp-4.2.8p4-i486-1_slack14.1.txz: Upgraded.

VAR-201510-0254 CVE-2015-5945 Apple OS X Privileged Vulnerability in Sandbox Subsystem CVSS V2: 7.2
CVSS V3: -
Severity: HIGH
The Sandbox subsystem in Apple OS X before 10.11.1 allows local users to gain privileges via vectors involving NVRAM parameters. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, cause denial-of-service conditions, bypass security restrictions and perform unauthorized actions. This may aid in other attacks. Sandbox is a sandbox system that provides the operating system with a method to limit the use of system resources by applications. The vulnerability is caused by the program's failure to validate input when processing NVRAM parameters. A local attacker could exploit this vulnerability to gain privileges. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 APPLE-SA-2015-10-21-4 OS X El Capitan 10.11.1 and Security Update 2015-007 OS X El Capitan 10.11.1 and Security Update 2015-007 are now available and address the following: Accelerate Framework Available for: OS X Mavericks v10.9.5, OS X Yosemite v10.10.5, and OS X El Capitan 10.11 Impact: Visiting a maliciously crafted website may lead to arbitrary code execution Description: A memory corruption issue existed in the Accelerate Framework in multi-threading mode.
