Multiple unspecified format string vulnerabilities in multiple unspecified implementations of Internet Key Exchange version 1 (IKEv1) have multiple unspecified attack vectors and impacts, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of information in the original sources, it is likely that this candidate will be REJECTed once it is known which implementations are actually vulnerable.
