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-r1

 

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"
