A vulnerability has been discovered in dpkg, which allows for directory
traversal.

Background
=========
Debian package management system.

Affected packages
================
Package Vulnerable Unaffected

Impact
=====
Dpkg::Source::Archive in dpkg, the Debian package management system, is
prone to a directory traversal vulnerability. When extracting untrusted
source packages in v2 and v3 source package formats that include a
debian.tar, the in-place extraction can lead to directory traversal
situations on specially crafted orig.tar and debian.tar tarballs.

Workaround
