Comment 1 Takashi Iwai 2023-08-28 15:56:51 UTC 
The old flac code on SLE12-SP4 and older doesn't use safe_realloc_(), hence this bug isn't triggered.

I'm going to patch SUSE:SLE-15:Update/flac.
Comment 2 Takashi Iwai 2023-08-29 06:49:10 UTC 
The fix for SLE15 is submitted.
Comment 4 Gianluca Gabrielli 2023-08-29 09:30:16 UTC 
I guess the two following codestreams also requires a submission:

- SUSE:ALP:Source:Standard:1.0/flac
- openSUSE:Factory/flac

Those are already v1.4.3 that includes the fix (the bug was old!)

Sorry, and thanks for your prompt reply.
