July 05, 2018

devscripts vulnerability
==========================================================================

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

- - Ubuntu 18.04 LTS
- - Ubuntu 17.10

Summary:

devscripts could be made to run arbitrary code if it received
a specially crafted YAML file.

Software Description:
- - devscripts: scripts to make the life of a Debian Package maintainer
easier

Details:

It was discovered that devscripts incorrectly handled certain YAML
files. An attacker could possibly use this to execute arbitrary code.

Update instructions:

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

Ubuntu 18.04 LTS:
   devscripts                                            2.17.12ubuntu1.1

Ubuntu 17.10:
   devscripts                                            2.17.9ubuntu0.1

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