CVE-2017-3732

TITLE

OpenSSL Service disruption in (DoS) Vulnerabilities

DESCRIPTION

There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL 1.0.2 before 1.0.2k and 1.1.0 before 1.1.0d. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH are considered just feasible (although very difficult) because most of the work necessary to deduce information about a private key may be performed offline. The amount of resources required for such an attack would be very significant and likely only accessible to a limited number of attackers. An attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example this can occur by default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very similar to CVE-2015-3193 but must be treated as a separate problem. OpenSSL There is a service disruption ( crash ) There are vulnerabilities that are put into a state.Service operation interruption ( crash ) There is a possibility of being put into a state. OpenSSL is prone to an information-disclosure vulnerability. An attacker can exploit this issue to gain access to sensitive information that may aid in further attacks. Versions prior to OpenSSL 1.1.0d and 1.0.2k are vulnerable. OpenSSL Security Advisory [07 Dec 2017] ======================================== Read/write after SSL object in error state (CVE-2017-3737) ========================================================== Severity: Moderate OpenSSL 1.0.2 (starting from version 1.0.2b) introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for the explicit handshake functions (SSL_do_handshake(), SSL_accept() and SSL_connect()), however due to a bug it does not work correctly if SSL_read() or SSL_write() is called directly. In that scenario, if the handshake fails then a fatal error will be returned in the initial function call. If SSL_read()/SSL_write() is subsequently called by the application for the same SSL object then it will succeed and the data is passed without being decrypted/encrypted directly from the SSL/TLS record layer. In order to exploit this issue an application bug would have to be present that resulted in a call to SSL_read()/SSL_write() being issued after having already received a fatal error. OpenSSL 1.0.2 users should upgrade to 1.0.2n This issue was reported to OpenSSL on 10th November 2017 by David Benjamin (Google). The fix was proposed by David Benjamin and implemented by Matt Caswell of the OpenSSL development team. rsaz_1024_mul_avx2 overflow bug on x86_64 (CVE-2017-3738) ========================================================= Severity: Low There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. This only affects processors that support the AVX2 but not ADX extensions like Intel Haswell (4th generation). Due to the low severity of this issue we are not issuing a new release of OpenSSL 1.1.0 at this time. The fix will be included in OpenSSL 1.1.0h when it becomes available. The fix is also available in commit e502cc86d in the OpenSSL git repository. OpenSSL 1.0.2 users should upgrade to 1.0.2n This issue was reported to OpenSSL on 22nd November 2017 by David Benjamin (Google). The issue was originally found via the OSS-Fuzz project. The fix was developed by Andy Polyakov of the OpenSSL development team. Note ==== Support for version 1.0.1 ended on 31st December 2016. Support for versions 0.9.8 and 1.0.0 ended on 31st December 2015. Those versions are no longer receiving security updates.
