CVE-2015-3193 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:14.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl098 package and not the openssl098 package as distributed by Ubuntu.
The Montgomery squaring implementation in crypto/bn/asm/x86_64-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x86_64 platform, as used by the BN_mod_exp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key information via an attack against use of a (1) Diffie-Hellman (DH) or (2) Diffie-Hellman Ephemeral (DHE) ciphersuite.
