5. An unspecified vulnerability in the BGP (Border Gateway) dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file possibly to cause a denial of sevice;
6. Multiple unspecified vulnerabilities in the DOF dissector, in the PacketBB dissector and in the SLSK dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file possibly to cause a denial of sevice;
7. Multiple unspecified vulnerabilities in the SIGCOMP (Signaling Compression) dissector and in the WSP (Wireless Session Protocol) dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file possibly to cause a denial of sevice.
