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.
