USN-2341-1: CUPS vulnerabilities

Releases

• Ubuntu 14.04 ESM
• Ubuntu 12.04
• Ubuntu 10.04

Packages

• 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

• cups - 1.7.2-0ubuntu1.2

Ubuntu 12.04

• cups - 1.5.3-0ubuntu8.5

Ubuntu 10.04

• cups - 1.4.3-1ubuntu1.13

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