Summary
Gentoo Linux Security Advisory GLSA 200812-15
https://security.gentoo.org/
Severity: Normal
Title: POV-Ray: User-assisted execution of arbitrary code
Date: December 14, 2008
Bugs: #153538
ID: 200812-15
Synopsis
=======
POV-Ray includes a version of libpng that might allow for the execution
of arbitrary code when reading a specially crafted PNG file
Background
=========
POV-Ray is a well known open-source ray tracer.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-gfx/povray < 3.6.1-r4 >= 3.6.1-r4
==========
POV-Ray uses a statically linked copy of libpng to view and output PNG
files. The version shipped with POV-Ray is vulnerable to CVE-2008-3964,
CVE-2008-1382, CVE-2006-3334, CVE-2006-0481, CVE-2004-0768. A bug in
POV-Ray's build system caused it to load the old version when your
installed copy of libpng was >=media-libs/libpng-1.2.10.
Impact
=====
An attacker could entice a user to load a specially crafted PNG file as
a texture, resulting in the execution of arbitrary code with the
permissions of the user running the application.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
All POV-Ray users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4"
