lintian vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS

Summary:

lintian could be made to run programs if it processed a specially crafted
package.

Software Description:
- lintian: Debian package checker

Details:

Jakub Wilk discovered that lintian incorrectly handled deserializing
certain YAML files. If a user or automated system were tricked into running
lintian on a specially crafted package, a remote attacker could possibly
use this issue to execute arbitrary code.

Update instructions:

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

Ubuntu 17.04:
lintian 2.5.50.1ubuntu0.1

Ubuntu 16.10:
lintian 2.5.48ubuntu0.1

Ubuntu 16.04 LTS:
lintian 2.5.43ubuntu0.1

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