TITLE

OpenSSL Vulnerability in

DESCRIPTION

There is a carry propagating bug in the x86_64 Montgomery squaring procedure in OpenSSL before 1.0.2m and 1.1.0 before 1.1.0g. 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. This only affects processors that support the BMI1, BMI2 and ADX extensions like Intel Broadwell (5th generation) and later or AMD Ryzen. 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 1.1.0g and 1.0.2m are vulnerable. OpenSSL Security Advisory [27 Mar 2018] ======================================== Constructed ASN.1 types with a recursive definition could exceed the stack (CVE-2018-0739) ========================================================================================== Severity: Moderate Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. OpenSSL 1.1.0 users should upgrade to 1.1.0h OpenSSL 1.0.2 users should upgrade to 1.0.2o This issue was reported to OpenSSL on 4th January 2018 by the OSS-fuzz project. The fix was developed by Matt Caswell of the OpenSSL development team. Incorrect CRYPTO_memcmp on HP-UX PA-RISC (CVE-2018-0733) ======================================================== Severity: Moderate Because of an implementation bug the PA-RISC CRYPTO_memcmp function is effectively reduced to only comparing the least significant bit of each byte. This allows an attacker to forge messages that would be considered as authenticated in an amount of tries lower than that guaranteed by the security claims of the scheme. The module can only be compiled by the HP-UX assembler, so that only HP-UX PA-RISC targets are affected. OpenSSL 1.1.0 users should upgrade to 1.1.0h This issue was reported to OpenSSL on 2nd March 2018 by Peter Waltenberg (IBM). The fix was developed by Andy Polyakov of the OpenSSL development team. Due to the low severity no fix was released at that time for OpenSSL 1.1.0. Note: The impact from this issue is similar to CVE-2017-3736, CVE-2017-3732 and CVE-2015-3193. OpenSSL 1.1.0 users should upgrade to 1.1.0h 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.
