Description

Hewlett-Packard Linux Imaging and Printing (HPLIP) provides drivers for
Hewlett-Packard (HP) printers and multifunction peripherals.

It was found that the HP CUPS (Common UNIX Printing System) fax filter in
HPLIP created a temporary file in an insecure way. A local attacker could
use this flaw to perform a symbolic link attack, overwriting arbitrary
files accessible to a process using the fax filter (such as the
hp3-sendfax tool). (CVE-2011-2722)

This update also fixes the following bug:

• Previous modifications of the hplip3 package to allow it to be installed

alongside the original hplip package introduced several problems to fax
support; for example, the hp-sendfax utility could become unresponsive.
These problems have been fixed with this update. (BZ#501834)

All users of hplip3 are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
