Description:
Stefan Esser has reported a vulnerability in KisMAC, which potentially can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the "WavePacket:parseTaggedData()" function when parsing the Cisco vendor tag for additional SSIDs in a received 802.11 management frame. This can be exploited to cause a stack-based buffer overflow and potentially allows arbitrary code execution.

Successful exploitation requires that the user is e.g. tricked into opening a malicious pcap file containing special-crafted management frames, or via raw management frames that are sent onto the wireless network while the user is performing a passive network scan.

The vulnerability has been reported in versions prior to R73p and is reportedly introduced in version R54.
