Description Agostino Sarubbo gentoo-dev 2016-03-17 11:42:31 UTC
From ${URL} :

A vulnerability was found in libvpx. A maliciously crafted media file allows remote attackers to execute arbitrary code or cause a denial of service. 

Upstream fix:!/#F1


@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Alexis Ballier gentoo-dev 2016-03-17 21:11:27 UTC
libvpx < 1.4.0 does not have libwebm

libvpx-1.4.0, diff from their mkvparser.cpp and android's libvpx from the link above is these two commits:

libvpx-1.5.0 has a much more recent libwebm

the report is definitely not clear; I'm not sure if the above 2 commits are related or if libvpx 1.4.0 is fine

anyway, severity isn't so high: libwebm is only used for vpxdec & vpxenc in libvpx; those are the examples programs that are barely used: they read/write vpx files and write/read raw videos from the disk

  and 6.0 before 2016-03-01 allows remote attackers to execute arbitrary code
  or cause a denial of service (memory corruption) via a crafted media file,
  related to libwebm/mkvparser.cpp and other files, aka internal bug 23452792.
Comment 3 Thomas Deutschmann gentoo-dev 2016-11-21 16:05:00 UTC
=media-libs/libvpx-1.4.0 is definitely affected.

=media-libs/libvpx-1.5.0 is the first version containing the fixes.

Stabilisation was completed in bug #585350 and I've now removed vulnerable.
