3. Description:

The hplip packages contain the Hewlett-Packard Linux Imaging and Printing Project (HPLIP), which provides drivers for Hewlett-Packard printers and multi-function peripherals.

Several temporary file handling flaws were found in HPLIP. A local attacker could use these flaws to perform a symbolic link attack, overwriting arbitrary files accessible to a process using HPLIP. (CVE-2013-0200, CVE-2011-2722)

The CVE-2013-0200 issues were discovered by Tim Waugh of Red Hat.

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. (BZ#731900)

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. (BZ#829453)

* 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. (BZ#683007)

All users of hplip are advised to upgrade to these updated packages, which fix these issues and add these enhancements.
