Description Sandipan Roy 2022-10-31 05:22:40 UTC

In dissect_opus() at wireshark-3.6.8/epan/dissectors/packet-opus.c:254, frame_count is truncated below 0x3F (63) and checked if framesize * frame_count > 120 * MAX_FRAMES_COUNT. But when stack variable frames[MAX_FRAMES_COUNT] is indexed with frame_count later, we didn't make sure frame_count won't excess MAX_FRAMES_COUNT, leading to stack-over-flow write when the begin/size values are put into frames later.
This flaw affects the current released stable wireshark/tshark/... on Linux/Windows/Mac/..., previous versions may also be affected. This issue hasn't been reported elsewhere.
