A vulnerability was discovered in dpkg which could potentially lead to
arbitrary code execution.

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

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------

Description
===========
Gentoo Linux developer, Hanno B=C3=B6ck, discovered an off-by-one error i=n
the dpkg-deb component of dpkg, the Debian package management system,
