USN-2566-1: dpkg vulnerability

9 April 2015

dpkg could be tricked into bypassing source package signature checks.



  • dpkg - Debian package management system


Jann Horn discovered that dpkg incorrectly validated signatures when
extracting local source packages. If a user or an automated system were
tricked into unpacking a specially crafted source package, a remote
attacker could bypass signature verification checks.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.10
Ubuntu 14.04
Ubuntu 12.04
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
