SSL: OpenSSL DTLS Recursion Denial of Service
This signature detects attempts to exploit a known flaw in OpenSSL. The vulnerability is due to the possibility of unbounded recursion in dtls1_get_message_fragment() during the processing of DTLS handshake messages. A remote, unauthenticated attacker could exploit this vulnerability by sending a malicious DTLS handshake to a target. Successful exploitation could lead to a denial-of-service condition.
