4.56. hplip3

Updated hplip3 packages that fix one security issue and one bug are now available for Red Hat Enterprise Linux 5.
The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) associated with each description below.
Hewlett-Packard Linux Imaging and Printing (HPLIP) provides drivers for Hewlett-Packard (HP) printers and multifunction peripherals.

Security Fix

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).

Bug Fix

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