SSL: GnuTLS TLS Record Decoding Out-of-bounds Memory Access
This signature detects attempts to exploit a known vulnerability in in GnuTLS. The vulnerability is due to an error in the function _gnutls_ciphertext2compressed(). A remote attacker could exploit this vulnerability to cause an affected server or a client application to crash resulting in a denial-of-service condition.
