Description

The Cryptographic Message Syntax (CMS) implementation in crypto/cms/cms_asn1.c in OpenSSL before 0.9.8o and 1.x before 1.0.0a does not properly handle structures that contain OriginatorInfo, which allows context-dependent attackers to modify invalid memory locations or conduct double-free attacks, and possibly execute arbitrary code, via unspecified vectors.

Affected products

OpenSSL: through 0.9.8n; 0.9.1c, 0.9.2b, 0.9.3, 0.9.3a, 0.9.4, 0.9.5 (+65)
