Kismet: Multiple vulnerabilities

1. Gentoo Linux Security Advisory

Package	Vulnerable versions	Unaffected versions	Architecture(s)
net-wireless/kismet	< 2005.08.1	>= 2005.08.1	All supported architectures

Related bugreports: #102702

Kismet is vulnerable to multiple issues potentially resulting in the execution of arbitrary code.

2. Impact Information

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

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

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

3. Resolution Information

There is no known workaround at this time.

All Kismet users should upgrade to the latest version:

Code Listing 3.1: Resolution

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