Gentoo Linux Security Advisory

Title: POV-Ray: User-assisted execution of arbitrary code (GLSA 200812-15)
Severity: normal
Exploitable: local
Date: December 14, 2008
Bug(s): #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: media-gfx/povray
Vulnerable: < 3.6.1-r4
Unaffected: >= 3.6.1-r4
Architectures: All supported architectures


Description


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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-gfx/povray-3.6.1-r4"
