Synopsis

========

 

A vulnerability in CUPS might allow for the execution of arbitrary code

or a Denial of Service.

 

Background

==========

 

CUPS provides a portable printing layer for UNIX-based operating

systems.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-print/cups < 1.2.12-r8 >= 1.2.12-r8

 

Description

===========

 

Thomas Pollet reported a possible integer overflow vulnerability in the

PNG image handling in the file filter/image-png.c.

 

Impact

======

 

A malicious user might be able to execute arbitrary code with the

privileges of the user running CUPS (usually lp), or cause a Denial of

Service by sending a specially crafted PNG image to the print server.

The vulnerability is exploitable via the network if CUPS is sharing

printers remotely.

 

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-1.2.12-r8"
