CVSS V3: -
Severity: MEDIUM
The xsltStylePreCompute function in preproc.c in libxslt 1.1.28 does not check if the parent node is an element, which allows attackers to cause a denial of service via a crafted XML file, related to a "type confusion" issue. libxslt is prone to a remote denial-of-service vulnerability. Attackers can exploit this issue to cause denial-of-service condition. libxslt 1.1.28 is vulnerable; other versions may also be affected. libxslt is an XSLT (XML language for defining XML transformations) C library developed for the GNOME project. The vulnerability is caused by the fact that the program does not check whether the parent node is an element. For the stable distribution (jessie), these problems have been fixed in version 1.1.28-2+deb8u1. We recommend that you upgrade your libxslt packages. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 APPLE-SA-2016-03-21-2 watchOS 2.2 watchOS 2.2 is now available and addresses the following: Disk Images Available for: Apple Watch Sport, Apple Watch, Apple Watch Edition, and Apple Watch Hermes Impact: An application may be able to execute arbitrary code with kernel privileges Description: A memory corruption issue existed in the parsing of disk images.

Description: The libxml2 library is a development toolbox providing the implementation of various XML standards. Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application.

It was discovered that ntpd as a client did not correctly check timestamps in Kiss-of-Death packets. (CVE-2015-7704) It was found that ntpd did not correctly implement the threshold limitation for the '-g' option, which is used to set the time without any restrictions. A man-in-the-middle attacker able to intercept NTP traffic between a connecting client and an NTP server could use this flaw to force that client to make multiple steps larger than the panic threshold, effectively changing the time to an arbitrary value. (CVE-2015-5300) Red Hat would like to thank Aanchal Malhotra, Isaac E. Cohen, and Sharon Goldberg of Boston University for reporting these issues.

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.

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. 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. 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. 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.
