Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the demux_audio function of the TY demuxer when processing a crafted ffconcat file with the -safe 0 flag. An attacker can achieve heap corruption and potentially execute arbitrary code or cause a denial of service by supplying a specially crafted input file that manipulates packet size, leading to unchecked memory operations in the Shorten decoder.
