Synopsis
========

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

Background
==========

Debian package management system.

Affected packages
=================

Package        Vulnerable    Unaffected
-------------  ------------  ------------
app-arch/dpkg  < 1.20.9-r1   >= 1.20.9-r1

Description
===========

Please review the CVE indentifier referenced below for details.

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
==========

There is no known workaround at this time.

Resolution
==========

All dpkg users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-arch/dpkg-1.20.9-r1"
