Summary

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.
