Hi, thanks for reporting this.
As there is no maintainer for this package I added the committers in CC.

(Please set the status to 'assigned' if you are working on it)

CC: (none) => mageia, ouaurelien, smelror
Assignee: bugsquad => pkg-bugs

The fix for the CVE's that's included in 4.3.2 are already in MGA8, however I plan on pushing 4.3.2 as an update as soon as Mageia 8 is released.

Cheers,
Stig

removed and re-submitted

Tested ffplay with an AVI file I recorded years ago with my TV card (core/updates_testing version) and it works fine on Mageia 8 x86_64.  Someone needs to test the tainted version.

Testing:

$ rpm -qa | grep ffmpeg
ffmpeg-4.3.2-1.mga8.tainted

No more missing signature as per comment 5 to 7.

Installed over existing version OK.
Reading and encoding files OK.

Giving this OK for tainted version.
As core version OK'ed in comment 8, MGA8-64-OK.

Thus, validating.
(and reassigning as security bug, per advisory)

@David, do we need to push this and open a new bug report on this?

Keywords: advisory, validated_update => (none)

We don't update to newer ffmpeg branches on stable releases, as it breaks things.  We'll expect security fixes to get backported to a 4.3.3 release upstream.  If needed, we can ask Michael N., the upstream maintainer, to produce such an update.

So let's push this version 4.3.2 to core/updates and open a new bug report for fixes in FFmpeg 4.4.
