Upgrade SLES:15.3 libavutil-devel to version 3.4.2-11.3.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libavutil-devel package and not the libavutil-devel package as distributed by SLES.
See How to fix? for SLES:15.3 relevant fixed versions and status.
FFmpeg 2.8 and 4.2.3 has a use-after-free via a crafted EXTINF duration in an m3u8 file because parse_playlist in libavformat/hls.c frees a pointer, and later that pointer is accessed in av_probe_input_format3 in libavformat/format.c.
