OpenSSL CMS code execution

openssl-cms-code-execution (59039) The risk level is classified as HighHigh Risk

Description:

OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an error when handling CMS (Cryptographic Message Syntax) structures. If CMS is enabled, a remote attacker could exploit this vulnerability using a specially-crafted CMS structure containing an "OriginatorInfo" element to trigger a double-free or a write to invalid memory addresses to execute arbitrary code on the system.
