Name of the Vulnerable Software and Affected Versions FFmpeg version 4.3.1
Description The issue is related to an out-of-bounds write in the track header function of the libavformat library in FFmpeg, caused by incorrect extradata packing. This can potentially allow a remote attacker to cause a denial of service.
