Details

Francisco Alonso discovered that the CUPS web interface incorrectly
validated permissions on rss files. A local 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
Ubuntu 12.04
Ubuntu 10.04

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