Publication date

10 June 2014

Overview

A malicious source package could write files outside the unpack directory.

Releases

Packages

  • dpkg - Debian package management system

Details

It was discovered that dpkg incorrectly handled certain patches when
unpacking source packages. If a user or an automated system were tricked
into unpacking a specially crafted source package, a remote attacker could
modify files outside the target unpack directory, leading to a denial of
service or potentially gaining access to the system.
