NVD Description

Note: Versions mentioned in the description apply only to the upstream ffmpeg-4-libavresample-devel package and not the ffmpeg-4-libavresample-devel package as distributed by SLES. See How to fix? for SLES:15.7 relevant fixed versions and status.

FFmpeg before commit 65b0dab contains an out-of-bounds read in the DASH demuxer (libavformat/dashdec.c). When a live DASH manifest is refreshed with a startNumber that is lower than the previous value, the current sequence number is driven negative. The fragment retrieval function checked only the upper bound before indexing the fragments array, allowing a negative index to be used and causing an out-of-bounds read. A malicious or misconfigured DASH server can trigger this by serving a live manifest with a decreasing startNumber across a manifest refresh.
