Red Hat Security Advisory 2014-1054-01 - OpenSSL is a toolkit that implements the Secure Sockets Layer, Transport Layer Security, and Datagram Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execute arbitrary code.
