Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

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

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

CUPS is the Common Unix Printing System.

Affected packages
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

      -------------------------------------------------------------------=

       Package         /  Vulnerable  /                       Unaffected
      -------------------------------------------------------------------=


    1  net-print/cups     < 1.3.9-r1                         >=3D 1.3.9-r=
1

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

None this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All CUPS users should upgrade to the latest version.

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=3Dnet-print/cups-1.3.9-r1"
