CVE-2015-4000

TITLE

TLS Encryption problem vulnerability

DESCRIPTION

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. OpenSSL is prone to a security-bypass vulnerability because the application fails to properly verify SSL, TLS, and DTLS certificates. Successfully exploiting this issue allows attackers to perform man-in-the-middle attacks and bypass certain security restrictions. This may aid in further attacks. OpenSSL versions 1.0.2c, 1.0.2b, 1.0.1n, and 1.0.1o are vulnerable. 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. 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. 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.

CVE-2015-4000 David Adrian et al. reported that it may be feasible to attack Diffie-Hellman-based cipher suites in certain circumstances, compromising the confidentiality and integrity of data encrypted with Transport Layer Security (TLS). CVE-2015-7181 CVE-2015-7182 CVE-2016-1950 Tyson Smith, David Keeler, and Francis Gabriel discovered heap-based buffer overflows in the ASN.1 DER parser, potentially leading to arbitrary code execution. CVE-2015-7575 Karthikeyan Bhargavan discovered that TLS client implementation accepted MD5-based signatures for TLS 1.2 connections with forward secrecy, weakening the intended security strength of TLS connections. CVE-2016-1938 Hanno Boeck discovered that NSS miscomputed the result of integer division for certain inputs. This could weaken the cryptographic protections provided by NSS. However, NSS implements RSA-CRT leak hardening, so RSA private keys are not directly disclosed by this issue. CVE-2016-1978 Eric Rescorla discovered a user-after-free vulnerability in the implementation of ECDH-based TLS handshakes, with unknown consequences. CVE-2016-1979 Tim Taubert discovered a use-after-free vulnerability in ASN.1 DER processing, with application-specific impact. CVE-2016-2834 Tyson Smith and Jed Davis discovered unspecified memory-safety bugs in NSS. In addition, the NSS library did not ignore environment variables in processes which underwent a SUID/SGID/AT_SECURE transition at process start. In certain system configurations, this allowed local users to escalate their privileges. For the stable distribution (jessie), these problems have been fixed in version 2:3.26-1+debu8u1. For the unstable distribution (sid), these problems have been fixed in version 2:3.23-1. We recommend that you upgrade your nss packages.
