cups vulnerabilities
==========================
==========================
========================

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

- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

CUPS could be made to expose sensitive information, leading to privilege
escalation.

Software Description:
- cups: Common UNIX Printing System(tm)

Details:

Salvatore Bonaccorso discovered that the CUPS web interface incorrectly
validated permissions and incorrectly handled symlinks. An attacker could=

possibly use this issue to bypass file permissions and read arbitrary
files, possibly leading to a privilege escalation.

Update instructions:

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

Ubuntu 14.04 LTS:
cups 1.7.2-0ubuntu1.2

Ubuntu 12.04 LTS:
cups 1.5.3-0ubuntu8.5

Ubuntu 10.04 LTS:
cups 1.4.3-1ubuntu1.13

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