Kismet: Multiple vulnerabilities

Background

Kismet is an 802.11 Layer 2 wireless network detector, sniffer, and intrusion detection system.

Description

Kismet is vulnerable to a heap overflow when handling pcap captures and to an integer underflow in the CDP protocol dissector.

Impact

With a specially crafted packet an attacker could cause Kismet to execute arbitrary code with the rights of the user running the program.

Workaround

There is no known workaround at this time.

Resolution

All Kismet users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-wireless/kismet-2005.08.1"
