Description Huzaifa S. Sidhpurwala 2014-06-02 07:25:42 UTC 
As per the upstream advisory:

By sending an invalid DTLS handshake to an OpenSSL DTLS client, the code can be made to recurse, eventually crashing in a DoS attack.

Only applications using OpenSSL as a DTLS client are affected.

OpenSSL 0.9.8 DTLS users should upgrade to 0.9.8za
OpenSSL 1.0.0 DTLS users should upgrade to 1.0.0m.
OpenSSL 1.0.1 DTLS users should upgrade to 1.0.1h.
.
