Comment 1 Carlos López 2021-12-03 11:10:48 UTC
SUSE:SLE-15-SP2:Update is affected. The fix was already introduced in openSUSE:Factory.

This bug was fixed with the same patch as #1193365 [0], as it affects the same component. Just like with that issue, I was not able to reproduce the crash, but the vulnerable code is present.

I'll try to take over.
Comment 3 Petr Gajdos 2021-12-07 14:18:34 UTC
Yes, the poc does not seem to be applicable for 15sp2:

:/193366 # aomenc --pass=2 --rt --rate-hist=5 -o /dev/null ./poc1
Warning: Assuming --pass=2 implies --passes=2

Error: Unrecognized option --rt

Usage: aomenc <options> -o dst_filename src_filename 
Use --help to see the full list of options.
