To be vulnerable, the system must: * be running BIND that was built with \"--enable-native-pkcs11\" * be signing one or more zones with an RSA key * be able to receive queries from a possible attacker", "A flaw was found in bind. An assertion failure can occur when a specially crafted query for a zone signed with an RSA key. BIND must be compiled with \"--enable-native-pkcs11\" for the system to be affected. The highest threat from this vulnerability is to system availability." ],
