You should have filed the nv-codec-headers reports against ffmpeg, I have reassigned them.

Also 5.0.1 has the commit that fixes the issue

This CVE Bugzilla entry is for community support informational purposes only as it does not affect a package in a commercially supported Red Hat product. Refer to the dependent bugs for status of those individual community products.

Comment 5 hnguyen66 2022-06-06 19:49:34 UTC
Both ffmpeg version 5.0.1 (https://git.ffmpeg.org/gitweb/ffmpeg.git/shortlog/refs/tags/n5.0.1) and 4.4.2 (https://git.ffmpeg.org/gitweb/ffmpeg.git/shortlog/refs/tags/n4.4.2) contains the fix commit 757da974b21833529cc41bdcc9684c29660cdfa8. Can we update the CVE's affected range to reflect this?
