CUPS: Multiple vulnerabilities

Background

CUPS, the Common Unix Printing System, is a full-featured print server.

Description

Multiple vulnerabilities have been discovered in CUPS. Please review the CVE identifiers referenced below for details.

Impact

A remote attacker may be able to execute arbitrary code using specially crafted streams, IPP requests or files, or cause a Denial of Service (daemon crash or hang). A local attacker may be able to gain escalated privileges or overwrite arbitrary files. Furthermore, a remote attacker may be able to obtain sensitive information from the CUPS process or hijack a CUPS administrator authentication request.

Workaround

There is no known workaround at this time.

Resolution

All CUPS users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=net-print/cups-1.4.8-r1"

NOTE: This is a legacy GLSA. Updates for all affected architectures are available since September 03, 2011. It is likely that your system is already no longer affected by this issue.
