Synopsis
========

Multiple vulnerabilities have been found in CUPS, some of which may
allow execution of arbitrary code or local privilege escalation.

Background
==========

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

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-print/cups              < 1.4.8-r1               >= 1.4.8-r1

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.
