"Updated hplip packages that fix various security issues are now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The hplip (Hewlett-Packard Linux Imaging and Printing) packages
provide drivers for Hewlett-Packard printers and multifunction
peripherals.

A flaw was discovered in the hplip alert-mailing functionality. A
local attacker could elevate their privileges by using specially
crafted packets to trigger alert mails, which are sent by the root
account. (CVE-2008-2940)

A flaw was discovered in the hpssd message parser. By sending
specially crafted packets, a local attacker could cause a denial of
service, stopping the hpssd process. (CVE-2008-2941)

Users of hplip should upgrade to these updated packages, which contain
backported patches to correct these issues."
