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"
