lcms2 vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS

Summary:

Applications using the Little CMS library could be made to crash or
run programs as your login if it opened a specially crafted file.

Software Description:
- lcms2: Little CMS color management library

Details:

It was discovered that a double free() could occur when the intent handling
code in the Little CMS library detected an error. An attacker could use
this to specially craft a file that caused an application using the Little
CMS library to crash or possibly execute arbitrary code.

Update instructions:

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

Ubuntu 14.04 LTS:
  liblcms2-2                      2.5-0ubuntu4.1
  liblcms2-utils                  2.5-0ubuntu4.1

After a standard system update you need to restart applications using
Little CMS to make all the necessary changes.
