A null pointer dereference flaw was found in openssl. A remote attacker, able to control the arguments of the GENERAL_NAME_cmp function, could cause the application, compiled with openssl to crash resulting in a denial of service. The highest threat from this vulnerability is to system availability.
Mitigation
Applications not using the GENERAL_NAME_cmp of openssl are not vulnerable to this flaw. Even when this function is used, if the attacker can control both the arguments of this function, only then the attacker could trigger a crash.
