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	Architecture(s)
app-arch/dpkg	< 1.17.26	>= 1.17.26	All supported architectures

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

An attacker could potentially execute arbitrary code if an user or an automated system were tricked into processing a specially crafted Debian binary package (.deb).

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-1.17.26"
