==========================================================================
Ubuntu Security Notice USN-3584-1
February 26, 2018

sensible-utils vulnerability
==========================================================================

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

- Ubuntu 17.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

sensible-utils could be made to run programs as your login if it opened a
malicious URL.

Software Description:
- sensible-utils: Utilities for sensible alternative selection

Details:

Gabriel Corona discovered that sensible-utils incorrectly validated strings
when launcher a browser with the sensible-browser tool. A remote attacker
could possibly use this issue with a specially crafted URL to conduct an
argument injection attack and execute arbitrary code.

Update instructions:

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

Ubuntu 17.10:
  sensible-utils                  0.0.10ubuntu0.1

Ubuntu 16.04 LTS:
  sensible-utils                  0.0.9ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  sensible-utils                  0.0.9ubuntu0.14.04.1

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