This signature detects attempts to exploit a known vulnerability in OpenSSL. It is due to an error in the ssl3_get_record() function when handling TLS connections. A remote attacker can exploit this by crafting certain records in TLS packets. A successful attack can result in the termination of the affected service due to a read attempt at NULL, which leads to a denial-of-service condition.
OpenSSL is prone to a denial-of-service vulnerability caused by a NULL-pointer dereference. An attacker can exploit this issue to crash the affected application, denying service to legitimate users. OpenSSL versions 0.9.8f through 0.9.8m are vulnerable.
