A vulnerability has been found and corrected in openssl:

Incorrectly formatted ClientHello handshake message could cause
OpenSSL to parse past the end of the message. This allows an attacker
to crash an application using OpenSSL by triggering an invalid memory
access. Additionally, some applications may be vulnerable to expose
contents of a parsed OCSP nonce extension (CVE-2011-0014).
