Description Vincent Danen 2010-11-09 01:04:53 UTC
A recent Google Chrome update indicated there was a memory corruption flaw in libvpx [1].

Upstream changes to correct the flaw are here:


(the second is to fix some regressions introduced by the first patch, by the looks of things).

libvpx seems to only be used, currently, by gstreamer-plugins-bad-free.

Name: CVE-2010-4203
URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-4203

WebM libvpx (aka the VP8 Codec SDK), as used in Google Chrome before
7.0.517.44, allows remote attackers to cause a denial of service
(memory corruption) or possibly have unspecified other impact via
unknown vectors.

The first patchset is applied in F14, the second is not. Given this reproducer doesn't work in F14, I suspect the flaw is fixed there. We should still try to get the second patchset applied though.
