Description

A flaw was found in Wireshark. A heap-based buffer overflow vulnerability exists within the Bluetooth Audio/Video Remote Control Profile (AVRCP) protocol dissector. This flaw can be triggered by a local user processing a specially crafted Bluetooth AVRCP packet, which requires user interaction. Successful exploitation leads to a crash of the Wireshark application, resulting in a denial of service.
