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.
Extended Description
The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service (recursion and client crash) via a DTLS hello message in an invalid DTLS handshake.
