Doc Text:
A flaw was found in FreeRDP. A malicious Remote Desktop Protocol (RDP) server can send specially crafted media data to a connected client. This malformed data can trigger a heap out-of-bounds read vulnerability within the TSMF FFmpeg decoder, leading to the client application crashing. This can result in a denial of service for the client.

Description OSIDB Bzimport 2026-08-01 13:01:44 UTC
FreeRDP before 3.29.0 contains a heap out-of-bounds read vulnerability in the TSMF FFmpeg decoder when parsing AVC1 MPEG2VIDEOINFO media types with insufficient ExtraData. Attackers can send malformed media format data from a server to trigger a crash by reading fixed offsets without validating source buffer length.
