dav1d is an AV1 decoder.
In some circumstances, dav1d might treat an invalid frame as valid, resulting in a crash.
Malformed frame data can result in a denial of service.
Users should avoid parsing untrusted video with dav1d.
All dav1d users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/dav1d-1.2.0"
