Debian DSA-854-1 : tcpdump - infinite loop

medium Nessus Plugin ID 19962

Synopsis

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

Description

Simon Nielsen discovered that the BGP dissector in tcpdump, a powerful tool for network monitoring and data acquisition, does not properly handle a -1 return value from an internal function that decodes data packets. A specially crafted BGP packet can cause a denial of service via an infinite loop.

Solution

Upgrade the tcpdump package.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 3.8.3-5sarge1.
