Description Jan Lieskovsky 2012-11-29 16:11:25 UTC
A denial of service flaw was found in the way USB dissector of Wireshark, a network traffic analyzer, performed dissection of certain USB packet capture files. A remote attacker could provide a specially-crafted USB packet / packet capture that, when processed, would lead to excessive CPU consumption or into situation where tshark executable would enter an infinite loop, when trying to process the crafted packet / packet capture file.
