Description Jan Lieskovsky 2012-11-29 08:54:19 EST
A denial of service flaw was found in the way RTCP dissector of Wireshark, a network traffic analyzer, performed dissection of certain RTCP packet capture files. A remote attacker could provide a specially-crafted RTCP packet / packet capture that, once 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.
