Debian DSA-255-1 : tcpdump - infinite loop

high Nessus Plugin ID 15092

Synopsis

The remote Debian host is missing a security-related update.

Description

Andrew Griffiths and iDEFENSE Labs discovered a problem in tcpdump, a powerful tool for network monitoring and data acquisition. An attacker is able to send a specially crafted network packet which causes tcpdump to enter an infinite loop.

In addition to the above problem the tcpdump developers discovered a potential infinite loop when parsing malformed BGP packets. They also discovered a buffer overflow that can be exploited with certain malformed NFS packets.

Solution

Upgrade the tcpdump packages.

For the stable distribution (woody) these problems have been fixed in version 3.6.2-2.3.

The old stable distribution (potato) does not seem to be affected by these problems.
