3. Description:

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.
