CVE-2015-3197

TITLE

OpenSSL re-uses unsafe prime numbers in Diffie-Hellman protocol

DESCRIPTION

ssl/s2_srvr.c in OpenSSL 1.0.1 before 1.0.1r and 1.0.2 before 1.0.2f does not prevent use of disabled ciphers, which makes it easier for man-in-the-middle attackers to defeat cryptographic protection mechanisms by performing computations on SSLv2 traffic, related to the get_client_master_key and get_client_hello functions. OpenSSL may generate unsafe primes for use in the Diffie-Hellman protocol, which may lead to disclosure of enough information for an attacker to recover the private encryption key. Network traffic encrypted using an RSA-based SSL certificate may be decrypted if enough SSLv2 handshake data can be collected. This is known as the "DROWN" attack in the media. OpenSSL is prone to a security-bypass vulnerability. Successfully exploiting this issue may allow attackers to perform unauthorized actions. This may lead to other attacks. Cisco Unified Computing System Central Software is prone to an arbitrary command-execution vulnerability. An attacker can exploit this issue to execute system commands on the underlying operating system. This issue being tracked by Cisco Bug ID CSCut46961. OpenSSL Security Advisory [28th Jan 2016] ========================================= NOTE: SUPPORT FOR VERSION 1.0.1 WILL BE ENDING ON 31ST DECEMBER 2016. NO SECURITY FIXES WILL BE PROVIDED AFTER THAT DATE. UNTIL THAT TIME SECURITY FIXES ONLY ARE BEING APPLIED. DH small subgroups (CVE-2016-0701) ================================== Severity: High Historically OpenSSL usually only ever generated DH parameters based on "safe" primes. More recently (in version 1.0.2) support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be "safe". Where an application is using DH configured with parameters based on primes that are not "safe" then an attacker could use this fact to find a peer's private DH exponent. This attack requires that the attacker complete multiple handshakes in which the peer uses the same private DH exponent. For example this could be used to discover a TLS server's private DH exponent if it's reusing the private DH exponent or it's using a static DH ciphersuite. OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in TLS. It is not on by default. If the option is not set then the server reuses the same private DH exponent for the life of the server process and would be vulnerable to this attack. It is believed that many popular applications do set this option and would therefore not be at risk. OpenSSL before 1.0.2f will reuse the key if: - SSL_CTX_set_tmp_dh()/SSL_set_tmp_dh() is used and SSL_OP_SINGLE_DH_USE is not set. - SSL_CTX_set_tmp_dh_callback()/SSL_set_tmp_dh_callback() is used, and both the parameters and the key are set and SSL_OP_SINGLE_DH_USE is not used. This is an undocumted feature and parameter files don't contain the key. - Static DH ciphersuites are used. The key is part of the certificate and so it will always reuse it. This is only supported in 1.0.2. It will not reuse the key for DHE ciphers suites if: - SSL_OP_SINGLE_DH_USE is set - SSL_CTX_set_tmp_dh_callback()/SSL_set_tmp_dh_callback() is used and the callback does not provide the key, only the parameters. The callback is almost always used like this. Non-safe primes are generated by OpenSSL when using: - genpkey with the dh_rfc5114 option. This will write an X9.42 style file including the prime-order subgroup size "q". This is supported since the 1.0.2 version. Older versions can't read files generated in this way. - dhparam with the -dsaparam option. This has always been documented as requiring the single use. The fix for this issue adds an additional check where a "q" parameter is available (as is the case in X9.42 based parameters). This detects the only known attack, and is the only possible defense for static DH ciphersuites. This could have some performance impact. Additionally the SSL_OP_SINGLE_DH_USE option has been switched on by default and cannot be disabled. This could have some performance impact. This issue affects OpenSSL version 1.0.2. OpenSSL 1.0.2 users should upgrade to 1.0.2f OpenSSL 1.0.1 is not affected by this CVE because it does not support X9.42 based parameters. It is possible to generate parameters using non "safe" primes, but this option has always been documented as requiring single use and is not the default or believed to be common. However, as a precaution, the SSL_OP_SINGLE_DH_USE change has also been backported to 1.0.1r. This issue was reported to OpenSSL on 12 January 2016 by Antonio Sanso (Adobe). The fix was developed by Matt Caswell of the OpenSSL development team (incorporating some work originally written by Stephen Henson of the OpenSSL core team). SSLv2 doesn't block disabled ciphers (CVE-2015-3197) ==================================================== Severity: Low A malicious client can negotiate SSLv2 ciphers that have been disabled on the server and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled, provided that the SSLv2 protocol was not also disabled via SSL_OP_NO_SSLv2. This issue affects OpenSSL versions 1.0.2 and 1.0.1. OpenSSL 1.0.2 users should upgrade to 1.0.2f OpenSSL 1.0.1 users should upgrade to 1.0.1r This issue was reported to OpenSSL on 26th December 2015 by Nimrod Aviram and Sebastian Schinzel. The fix was developed by Nimrod Aviram with further development by Viktor Dukhovni of the OpenSSL development team. An update on DHE man-in-the-middle protection (Logjam) ==================================================================== A previously published vulnerability in the TLS protocol allows a man-in-the-middle attacker to downgrade vulnerable TLS connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. This vulnerability is known as Logjam (CVE-2015-4000). OpenSSL added Logjam mitigation for TLS clients by rejecting handshakes with DH parameters shorter than 768 bits in releases 1.0.2b and 1.0.1n. This limit has been increased to 1024 bits in this release, to offer stronger cryptographic assurance for all TLS connections using ephemeral Diffie-Hellman key exchange. OpenSSL 1.0.2 users should upgrade to 1.0.2f OpenSSL 1.0.1 users should upgrade to 1.0.1r The fix was developed by Kurt Roeckx 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 Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector(mod_jk), JBoss HTTP Connector (mod_cluster), Hibernate, and the Tomcat Native library. Relevant releases/architectures: RHEL 7-based RHEV-H - noarch RHEV Hypervisor for RHEL-6 - noarch 3. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. (CVE-2015-3197) A side-channel attack was found that makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture. An attacker who has the ability to control code in a thread running on the same hyper-threaded core as the victim's thread that is performing decryption, could use this flaw to recover RSA private keys. (CVE-2016-0702) A double-free flaw was found in the way OpenSSL parsed certain malformed DSA (Digital Signature Algorithm) private keys. An attacker could create specially crafted DSA private keys that, when processed by an application compiled against OpenSSL, could cause the application to crash. (CVE-2016-0705) An integer overflow flaw, leading to a NULL pointer dereference or a heap-based memory corruption, was found in the way some BIGNUM functions of OpenSSL were implemented. Applications that use these functions with large untrusted input could crash or, potentially, execute arbitrary code. Changes to the rhev-hypervisor component: * Previously, a race between services during boot prevented network configuration from upgrading correctly. The risk for the race has now been reduced significantly to allow the upgrade of the network configuration to complete correctly. (BZ#1194068) * Previously, using the text user interface (TUI) to log in to the administrator account of Red Hat Enterprise Virtualization Hypervisor failed with a Python backtrace. This update makes the "six" module correctly importable under all circumstances, which ensures that logging in to Red Hat Enterprise Virtualization Hypervisor using TUI proceeds as expected.

Corrected: 2016-01-28 21:42:10 UTC (stable/10, 10.2-STABLE) 2016-01-30 06:12:03 UTC (releng/10.2, 10.2-RELEASE-p12) 2016-01-30 06:12:03 UTC (releng/10.1, 10.1-RELEASE-p29) 2016-01-30 06:09:38 UTC (stable/9, 9.3-STABLE) 2016-01-30 06:12:03 UTC (releng/9.3, 9.3-RELEASE-p36) CVE Name: CVE-2015-3197 For general information regarding FreeBSD Security Advisories, including descriptions of the fields above, security branches, and the following sections, please visit <URL:https://security.FreeBSD.org/>. Background FreeBSD includes software from the OpenSSL Project. II. III. Impact An active MITM attacker may be able to force a protocol downgrade to SSLv2, which is a flawed protocol and intercept the communication between client and server. IV. Workaround No workaround is available, but only applications that do not explicitly disable SSLv2 are affected. To determine if a server have SSLv2 enabled, a system administrator can use the following command: % openssl s_client -ssl2 -connect <host>:<port> </dev/null 2>&1 | grep DONE which will print "DONE" if and only if SSLv2 is enabled. Note that this check will not work for services that uses STARTTLS or DTLS. 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. Restart all deamons using the library, or reboot the system. 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 Restart all deamons using the library, or reboot the system. 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.

Description: OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. A padding oracle flaw was found in the Secure Sockets Layer version 2.0 (SSLv2) protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. (CVE-2016-0800) Note: This issue was addressed by disabling the SSLv2 protocol by default when using the 'SSLv23' connection methods, and removing support for weak SSLv2 cipher suites. For more information, refer to the knowledge base article linked to in the References section. It was discovered that the SSLv2 servers using OpenSSL accepted SSLv2 connection handshakes that indicated non-zero clear key length for non-export cipher suites. An attacker could use this flaw to decrypt recorded SSLv2 sessions with the server by using it as a decryption oracle.(CVE-2016-0703) It was discovered that the SSLv2 protocol implementation in OpenSSL did not properly implement the Bleichenbacher protection for export cipher suites. An attacker could use a SSLv2 server using OpenSSL as a Bleichenbacher oracle. A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks. (CVE-2015-3197) Red Hat would like to thank the OpenSSL project for reporting these issues.
