Description Jan Lieskovsky 2012-03-28 10:40:55 UTC
A NULL pointer dereference flaw was found in the way ANSI A dissector of the Wireshark, a network traffic analyzer, processed certain capture files (those causing wireshark to pass NULL packet information via a global variable to the call_dissector() routine). A remote attacker could provide a specially-crafted packet capture file, which once opened by a local unsuspecting user would lead to wireshark executable crash.
