Debian DSA-2142-1 : dpkg - directory traversal

medium Nessus Plugin ID 51428

Language:

Synopsis

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

Description

Jakub Wilk discovered that the dpkg-source component of dpkg, the Debian package management system, doesn't correctly handle paths in patches of source packages, which could make it traverse directories.
Raphael Hertzog additionally discovered that symbolic links in the .pc directory are followed, which could make it traverse directories too.

Both issues only affect source packages using the '3.0 quilt' format at unpack-time.

Solution

Upgrade the dpkg packages.

For the stable distribution (lenny), these problems have been fixed in version 1.14.31.
