Synopsis
========
A vulnerability was discovered in dpkg which could potentially lead to
arbitrary code execution.
Background
==========
Debian package management system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/dpkg < 1.17.26 >= 1.17.26
Description
===========
Gentoo Linux developer, Hanno Böck, discovered an off-by-one error in
the dpkg-deb component of dpkg, the Debian package management system,
which triggers a stack-based buffer overflow.
Impact

automated system were tricked into processing a specially crafted
Debian binary package (.deb).
Workaround
==========

Resolution

All dpkg users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/dpkg-1.17.26"
