Red Hat Security Advisory 2012-0522-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. Multiple numeric conversion errors, leading to a buffer overflow, were found in the way OpenSSL parsed ASN.1 data from BIO inputs. Specially-crafted DER encoded data read from a file or other BIO input could cause an application using the OpenSSL library to crash or, potentially, execute arbitrary code.
