Description

Updated openssl packages fix security vulnerability There is a carry propagation bug in the Broadwell-specific Montgomery multiplication procedure that handles input lengths divisible by, but longer than 256 bits. mong EC algorithms only Brainpool P-512 curves are affected and one presumably can attack ECDH key negotiation (CVE-2016-7055). If an SSL/TLS server or client is running on a 32-bit host, and a specific cipher is being used, then a truncated packet can cause that server or client to perform an out-of-bounds read, usually resulting in a crash. The crash can be triggered when using RC4-MD5, if it has not been disabled (CVE-2017-3731). There is a carry propagating bug in the x86_64 Montgomery squaring procedure. An attacker would 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 (CVE-2017-3732).
