Synopsis
========
Several remotely exploitable bugs have been found in CUPS, which allow
remote execution of arbitrary code.

Background
==========
CUPS is the Common Unix Printing System.

Affected packages
=================
-------------------------------------------------------------------=
Package / Vulnerable / Unaffected
-------------------------------------------------------------------=
1 net-print/cups < 1.3.9-r1 >= 1.3.9-r=1

Description
===========
Several buffer overflows were found in:

* The read_rle16 function in imagetops (CVE-2008-3639, found by
regenrecht, reported via ZDI)

* The WriteProlog function in texttops (CVE-2008-3640, found by
regenrecht, reported via ZDI)

* The Hewlett-Packard Graphics Language (HPGL) filter (CVE-2008-3641,
found by regenrecht, reported via iDefense)

* The _cupsImageReadPNG function (CVE-2008-5286, reported by iljavs)

Impact
======
A remote attacker could send specially crafted input to a vulnerable
server, resulting in the remote execution of arbitrary code with the
privileges of the user running the server.

Workaround
==========
None this time.

Resolution
==========
All CUPS users should upgrade to the latest version.

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-print/cups-1.3.9-r1"
