Debian Bug : 1053182

Clement Lecigne discovered a heap-based buffer overflow in libvpx, a
multimedia library for the VP8 and VP9 video codecs, which may result in
the execution of arbitrary code if a specially crafted VP8 media stream
is processed.

For the oldstable distribution (bullseye), this problem has been fixed
in version 1.9.0-1+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in
version 1.12.0-1+deb12u1.

We recommend that you upgrade your libvpx packages.
