ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian packet filtering which would block these packets is in danger of having its time controlled by an attacker. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a remote security vulnerability. Successful exploits will allow attackers to bypass certain security restrictions and perform some unauthorized actions to the application. This may aid in further attacks. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 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.

An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 are vulnerable. ========================================================================== Ubuntu Security Notice USN-3096-1 October 05, 2016 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP.

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 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) * A denial of service flaw was found in the way NTP handled preemptable client associations. (CVE-2016-1547) * It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. (CVE-2016-1548) * A flaw was found in the way NTP's libntp performed message authentication. An attacker able to observe the timing of the comparison function used in packet authentication could potentially use this flaw to recover the message digest. (CVE-2016-1550) * An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. (CVE-2016-2518) The CVE-2016-1548 issue was discovered by Miroslav Lichvar (Red Hat). 4.

An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a local security-bypass vulnerability. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 are vulnerable. ========================================================================== Ubuntu Security Notice USN-3096-1 October 05, 2016 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP.

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 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) * A denial of service flaw was found in the way NTP handled preemptable client associations. A remote attacker could send several crypto NAK packets to a victim client, each with a spoofed source address of an existing associated peer, preventing that client from synchronizing its time. (CVE-2016-1547) * It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. A remote attacker could use a spoofed packet that, when processed by an ntpd client, would cause that client to reject all future legitimate server responses, effectively disabling time synchronization on that client. (CVE-2016-1548) * A flaw was found in the way NTP's libntp performed message authentication. (CVE-2016-1550) * An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. (CVE-2016-2518) The CVE-2016-1548 issue was discovered by Miroslav Lichvar (Red Hat). 4.

CVE-2015-7977 / CVE-2015-7978 Stephen Gray discovered that a NULL pointer dereference and a buffer overflow in the handling of "ntpdc reslist" commands may result in denial of service. CVE-2016-2518 Yihan Lian discovered that an OOB memory access could potentially crash ntpd. For the stable distribution (jessie), these problems have been fixed in version 1:4.2.6.p5+dfsg-7+deb8u2. For the testing distribution (stretch), these problems have been fixed in version 1:4.2.8p7+dfsg-1. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.8p7+dfsg-1. We recommend that you upgrade your ntp packages

An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer->dst timestamp recorded for that server. After making this switch, the client in NTP 4.2.8p4 and earlier and NTPSec aa48d001683e5b791a743ec9c575aaf7d867a2b0c will reject all future legitimate server responses. It is possible to force the victim client to move time after the mode has been changed. ntpq gives no indication that the mode has been switched. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a security-bypass vulnerability. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 are vulnerable. ========================================================================== Ubuntu Security Notice USN-3096-1 October 05, 2016 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP.

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 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) * A denial of service flaw was found in the way NTP handled preemptable client associations. A remote attacker could send several crypto NAK packets to a victim client, each with a spoofed source address of an existing associated peer, preventing that client from synchronizing its time. (CVE-2016-1547) * It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. (CVE-2016-1548) * A flaw was found in the way NTP's libntp performed message authentication. An attacker able to observe the timing of the comparison function used in packet authentication could potentially use this flaw to recover the message digest. (CVE-2016-1550) * An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. (CVE-2016-2518) The CVE-2016-1548 issue was discovered by Miroslav Lichvar (Red Hat). 4.

CVE-2015-7977 / CVE-2015-7978 Stephen Gray discovered that a NULL pointer dereference and a buffer overflow in the handling of "ntpdc reslist" commands may result in denial of service. CVE-2016-2518 Yihan Lian discovered that an OOB memory access could potentially crash ntpd. For the stable distribution (jessie), these problems have been fixed in version 1:4.2.6.p5+dfsg-7+deb8u2. For the testing distribution (stretch), these problems have been fixed in version 1:4.2.8p7+dfsg-1. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.8p7+dfsg-1. We recommend that you upgrade your ntp packages

A malicious authenticated peer can create arbitrarily-many ephemeral associations in order to win the clock selection algorithm in ntpd in NTP 4.2.8p4 and earlier and NTPsec 3e160db8dc248a0bcb053b56a80167dc742d2b74 and a5fb34b9cc89b92a8fef2f459004865c93bb7f92 and modify a victim's clock. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a remote security vulnerability. Successful exploits will allow attackers to bypass certain security restrictions and perform some unauthorized actions to the application. This may aid in further attacks. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 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.

Edge-case hole reported by Martin Burnicki of Meinberg. And fixes another security issue in ntpq and ntpdc: LOW: Sec 3505: The openhost() function used during command-line hostname processing by ntpq and ntpdc can write beyond its buffer limit, which could allow an attacker to achieve code execution or escalate to higher privileges via a long string as the argument for an IPv4 or IPv6 command-line parameter. NOTE: It is unclear whether there are any common situations in which ntpq or ntpdc is used with a command line from an untrusted source

NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (prevent subsequent authentication) by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey. NOTE: this vulnerability exists because of a CVE-2016-2516 regression. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP There is a service disruption ( Interfering with subsequent authentication ) There are vulnerabilities that are put into a state. NTP is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 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.

ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 are vulnerable. ========================================================================== Ubuntu Security Notice USN-3349-1 July 05, 2017 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.04 - Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS Summary: Several security issues were fixed in NTP.

NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service (ntpd abort) by using the same IP address multiple times in an unconfig directive. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. ========================================================================== Ubuntu Security Notice USN-3096-1 October 05, 2016 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP. Software Description: - ntp: Network Time Protocol daemon and utility programs Details: Aanchal Malhotra discovered that NTP incorrectly handled authenticated broadcast mode. A remote attacker could use this issue to perform a replay attack. (CVE-2015-7973) Matt Street discovered that NTP incorrectly verified peer associations of symmetric keys. A remote attacker could use this issue to perform an impersonation attack. (CVE-2015-7974) Jonathan Gardner discovered that the NTP ntpq utility incorrectly handled memory. This issue only affected Ubuntu 16.04 LTS. (CVE-2015-7975) Jonathan Gardner discovered that the NTP ntpq utility incorrectly handled dangerous characters in filenames. An attacker could possibly use this issue to overwrite arbitrary files. (CVE-2015-7976) Stephen Gray discovered that NTP incorrectly handled large restrict lists. (CVE-2015-7977, CVE-2015-7978) Aanchal Malhotra discovered that NTP incorrectly handled authenticated broadcast mode. (CVE-2015-7979) Jonathan Gardner discovered that NTP incorrectly handled origin timestamp checks. A remote attacker could use this issue to spoof peer servers. (CVE-2015-8138) Jonathan Gardner discovered that the NTP ntpq utility did not properly handle certain incorrect values. (CVE-2015-8158) It was discovered that the NTP cronjob incorrectly cleaned up the statistics directory. A local attacker could possibly use this to escalate privileges. (CVE-2016-0727) Stephen Gray and Matthew Van Gundy discovered that NTP incorrectly validated crypto-NAKs. A remote attacker could possibly use this issue to prevent clients from synchronizing. (CVE-2016-1547) Miroslav Lichvar and Jonathan Gardner discovered that NTP incorrectly handled switching to interleaved symmetric mode. A remote attacker could possibly use this issue to prevent clients from synchronizing. (CVE-2016-1548) Matthew Van Gundy, Stephen Gray and Loganaden Velvindron discovered that NTP incorrectly handled message authentication. A remote attacker could possibly use this issue to recover the message digest key. (CVE-2016-1550) Yihan Lian discovered that NTP incorrectly handled duplicate IPs on unconfig directives. (CVE-2016-2516) Yihan Lian discovered that NTP incorrectly handled certail peer associations. (CVE-2016-2518) Jakub Prokes discovered that NTP incorrectly handled certain spoofed packets. (CVE-2016-4954) Miroslav Lichvar discovered that NTP incorrectly handled certain packets when autokey is enabled. (CVE-2016-4955) Miroslav Lichvar discovered that NTP incorrectly handled certain spoofed broadcast packets. (CVE-2016-4956) In the default installation, attackers would be isolated by the NTP AppArmor profile.

The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value. The NTP.org reference implementation of ntpd contains multiple vulnerabilities. NTP is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition, denying service to legitimate users. Versions prior to NTP 4.2.8p7 and 4.3.x versions prior to 4.3.92 are vulnerable. ========================================================================== Ubuntu Security Notice USN-3096-1 October 05, 2016 ntp vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP.

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 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) * A denial of service flaw was found in the way NTP handled preemptable client associations. A remote attacker could send several crypto NAK packets to a victim client, each with a spoofed source address of an existing associated peer, preventing that client from synchronizing its time. (CVE-2016-1547) * It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. A remote attacker could use a spoofed packet that, when processed by an ntpd client, would cause that client to reject all future legitimate server responses, effectively disabling time synchronization on that client. (CVE-2016-1548) * A flaw was found in the way NTP's libntp performed message authentication. An attacker able to observe the timing of the comparison function used in packet authentication could potentially use this flaw to recover the message digest. (CVE-2016-1550) * An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash. (CVE-2016-2518) The CVE-2016-1548 issue was discovered by Miroslav Lichvar (Red Hat). 4.

The asn1_d2i_read_bio function in crypto/asn1/a_d2i_fp.c in the ASN.1 BIO implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (memory consumption) via a short invalid encoding. OpenSSL is prone to a local denial-of-service vulnerability. An attacker may exploit this issue to crash the application or consume excessive amount of data, resulting in denial-of-service conditions. OpenSSL Security Advisory [3rd May 2016] ======================================== Memory corruption in the ASN.1 encoder (CVE-2016-2108) ====================================================== Severity: High This issue affected versions of OpenSSL prior to April 2015. The bug causing the vulnerability was fixed on April 18th 2015, and released as part of the June 11th 2015 security releases. The security impact of the bug was not known at the time. In previous versions of OpenSSL, ASN.1 encoding the value zero represented as a negative integer can cause a buffer underflow with an out-of-bounds write in i2c_ASN1_INTEGER. The ASN.1 parser does not normally create "negative zeroes" when parsing ASN.1 input, and therefore, an attacker cannot trigger this bug. However, a second, independent bug revealed that the ASN.1 parser (specifically, d2i_ASN1_TYPE) can misinterpret a large universal tag as a negative zero value. Large universal tags are not present in any common ASN.1 structures (such as X509) but are accepted as part of ANY structures. Therefore, if an application deserializes untrusted ASN.1 structures containing an ANY field, and later reserializes them, an attacker may be able to trigger an out-of-bounds write. This has been shown to cause memory corruption that is potentially exploitable with some malloc implementations. Applications that parse and re-encode X509 certificates are known to be vulnerable. Applications that verify RSA signatures on X509 certificates may also be vulnerable; however, only certificates with valid signatures trigger ASN.1 re-encoding and hence the bug. Specifically, since OpenSSL's default TLS X509 chain verification code verifies the certificate chain from root to leaf, TLS handshakes could only be targeted with valid certificates issued by trusted Certification Authorities. OpenSSL 1.0.2 users should upgrade to 1.0.2c OpenSSL 1.0.1 users should upgrade to 1.0.1o This vulnerability is a combination of two bugs, neither of which individually has security impact. The first bug (mishandling of negative zero integers) was reported to OpenSSL by Huzaifa Sidhpurwala (Red Hat) and independently by Hanno Böck in April 2015. The second issue (mishandling of large universal tags) was found using libFuzzer, and reported on the public issue tracker on March 1st 2016. The fact that these two issues combined present a security vulnerability was reported by David Benjamin (Google) on March 31st 2016. The fixes were developed by Steve Henson of the OpenSSL development team, and David Benjamin. The OpenSSL team would also like to thank Mark Brand and Ian Beer from the Google Project Zero team for their careful analysis of the impact. The fix for the "negative zero" memory corruption bug can be identified by commits 3661bb4e7934668bd99ca777ea8b30eedfafa871 (1.0.2) and 32d3b0f52f77ce86d53f38685336668d47c5bdfe (1.0.1) Padding oracle in AES-NI CBC MAC check (CVE-2016-2107) ====================================================== Severity: High A MITM attacker can use a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server support AES-NI. This issue was introduced as part of the fix for Lucky 13 padding attack (CVE-2013-0169). The padding check was rewritten to be in constant time by making sure that always the same bytes are read and compared against either the MAC or padding bytes. But it no longer checked that there was enough data to have both the MAC and padding bytes. OpenSSL 1.0.2 users should upgrade to 1.0.2h OpenSSL 1.0.1 users should upgrade to 1.0.1t This issue was reported to OpenSSL on 13th of April 2016 by Juraj Somorovsky using TLS-Attacker. The fix was developed by Kurt Roeckx of the OpenSSL development team. EVP_EncodeUpdate overflow (CVE-2016-2105) ========================================= Severity: Low An overflow can occur in the EVP_EncodeUpdate() function which is used for Base64 encoding of binary data. If an attacker is able to supply very large amounts of input data then a length check can overflow resulting in a heap corruption. Internally to OpenSSL the EVP_EncodeUpdate() function is primarly used by the PEM_write_bio* family of functions. These are mainly used within the OpenSSL command line applications. These internal uses are not considered vulnerable because all calls are bounded with length checks so no overflow is possible. User applications that call these APIs directly with large amounts of untrusted data may be vulnerable. (Note: Initial analysis suggested that the PEM_write_bio* were vulnerable, and this is reflected in the patch commit message. This is no longer believed to be the case). OpenSSL 1.0.2 users should upgrade to 1.0.2h OpenSSL 1.0.1 users should upgrade to 1.0.1t This issue was reported to OpenSSL on 3rd March 2016 by Guido Vranken. The fix was developed by Matt Caswell of the OpenSSL development team. EVP_EncryptUpdate overflow (CVE-2016-2106) ========================================== Severity: Low An overflow can occur in the EVP_EncryptUpdate() function. If an attacker is able to supply very large amounts of input data after a previous call to EVP_EncryptUpdate() with a partial block then a length check can overflow resulting in a heap corruption. Following an analysis of all OpenSSL internal usage of the EVP_EncryptUpdate() function all usage is one of two forms. The first form is where the EVP_EncryptUpdate() call is known to be the first called function after an EVP_EncryptInit(), and therefore that specific call must be safe. The second form is where the length passed to EVP_EncryptUpdate() can be seen from the code to be some small value and therefore there is no possibility of an overflow. Since all instances are one of these two forms, it is believed that there can be no overflows in internal code due to this problem. It should be noted that EVP_DecryptUpdate() can call EVP_EncryptUpdate() in certain code paths. Also EVP_CipherUpdate() is a synonym for EVP_EncryptUpdate(). All instances of these calls have also been analysed too and it is believed there are no instances in internal usage where an overflow could occur. This could still represent a security issue for end user code that calls this function directly. OpenSSL 1.0.2 users should upgrade to 1.0.2h OpenSSL 1.0.1 users should upgrade to 1.0.1t This issue was reported to OpenSSL on 3rd March 2016 by Guido Vranken. The fix was developed by Matt Caswell of the OpenSSL development team. Any application parsing untrusted data through d2i BIO functions is affected. The memory based functions such as d2i_X509() are *not* affected. Since the memory based functions are used by the TLS library, TLS applications are not affected. OpenSSL 1.0.2 users should upgrade to 1.0.2h OpenSSL 1.0.1 users should upgrade to 1.0.1t This issue was reported to OpenSSL on 4th April 2016 by Brian Carpenter. The fix was developed by Stephen Henson of the OpenSSL development team. EBCDIC overread (CVE-2016-2176) =============================== Severity: Low ASN1 Strings that are over 1024 bytes can cause an overread in applications using the X509_NAME_oneline() function on EBCDIC systems. This could result in arbitrary stack data being returned in the buffer. OpenSSL 1.0.2 users should upgrade to 1.0.2h OpenSSL 1.0.1 users should upgrade to 1.0.1t This issue was reported to OpenSSL on 5th March 2016 by Guido Vranken. The fix was developed by Matt Caswell of the OpenSSL development team. Note ==== As per our previous announcements and our Release Strategy (https://www.openssl.org/policies/releasestrat.html), support for OpenSSL version 1.0.1 will cease on 31st December 2016. No security updates for that version will be provided after that date. Users of 1.0.1 are advised to upgrade. Support for versions 0.9.8 and 1.0.0 ended on 31st December 2015. Those versions are no longer receiving security updates.

Description: Red Hat JBoss Enterprise Application Platform 6 is a platform for Java applications based on JBoss Application Server 7. This release includes bug fixes and enhancements, as well as a new release of OpenSSL that addresses a number of outstanding security flaws. For further information, see the knowledge base article linked to in the References section. The JBoss server process must be restarted for the update to take effect. (CVE-2016-2108) * Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. (CVE-2015-3195) * A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange (for both export and non-export grade cipher suites). An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. (CVE-2016-2106) * It was discovered that it is possible to remotely Segfault Apache http server with a specially crafted string sent to the mod_cluster via service messages (MCMP). (CVE-2016-2109) * It was discovered that specifying configuration with a JVMRoute path longer than 80 characters will cause segmentation fault leading to a server crash. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: openssl security update Advisory ID: RHSA-2016:0722-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-0722.html Issue date: 2016-05-09 CVE Names: CVE-2016-0799 CVE-2016-2105 CVE-2016-2106 CVE-2016-2107 CVE-2016-2108 CVE-2016-2109 CVE-2016-2842 ===================================================================== 1. Summary: An update for openssl is now available for Red Hat Enterprise Linux 7. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2.

Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. Security Fix(es): * A flaw was found in the way OpenSSL encoded certain ASN.1 data structures. An attacker could use this flaw to create a specially crafted certificate which, when verified or re-encoded by OpenSSL, could cause it to crash, or execute arbitrary code using the permissions of the user running an application compiled against the OpenSSL library. A remote attacker could use these flaws to crash an application using OpenSSL or, possibly, execute arbitrary code with the permissions of the user running that application. (CVE-2016-2105, CVE-2016-2106) * It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when the connection used the AES CBC cipher suite and the server supported AES-NI. A remote attacker could possibly use this flaw to retrieve plain text from encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2016-0799, CVE-2016-2842) * A denial of service flaw was found in the way OpenSSL parsed certain ASN.1-encoded data from BIO (OpenSSL's I/O abstraction) inputs. (CVE-2016-2109) Red Hat would like to thank the OpenSSL project for reporting CVE-2016-2108, CVE-2016-2842, CVE-2016-2105, CVE-2016-2106, CVE-2016-2107, and CVE-2016-0799.
