Ubuntu: USN-5984-1 Important Security Patch for libav1 Buffer Overflow

Nick Galloway discovered an integer overflow in dav1d, a fast and small
AV1 video stream decoder which could result in memory corruption.

For the oldstable distribution (bullseye), this problem has been fixed
in version 0.7.1-3+deb11u1.

For the stable distribution (bookworm), this problem has been fixed in
version 1.0.0-2+deb12u1.

We recommend that you upgrade your dav1d packages.

For the detailed security status of dav1d please refer to
its security tracker page at:
