Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.29.0

Description A heap out-of-bounds read occurs in the TSMF FFmpeg decoder when parsing AVC1 MPEG2VIDEOINFO media types that have insufficient ExtraData. A remote attacker can trigger a crash by sending malformed media format data from a server, which causes the system to read fixed offsets without validating the source buffer length.
