(CVE-2013-0200, CVE-2011-2722)

The hplip packages have been upgraded to upstream version 3.12.4,
which provides a number of bug fixes and enhancements over the
previous version.

This update also fixes the following bugs :

  - Previously, the hpijs package required the obsolete
    cupsddk-drivers package, which was provided by the cups
    package. Under certain circumstances, this dependency
    caused hpijs installation to fail. This bug has been
    fixed and hpijs no longer requires cupsddk-drivers.

  - The configuration of the Scanner Access Now Easy (SANE)
    back end is located in the /etc/sane.d/dll.d/ directory,
    however, the hp-check utility checked only the
    /etc/sane.d/dll.conf file. Consequently, hp-check
    checked for correct installation, but incorrectly
    reported a problem with the way the SANE back end was
    installed. With this update, hp-check properly checks
    for installation problems in both locations as expected."

"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 from the
CVE link in the References section.

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."
