Description
AI Translation Available
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.29.0, planar_decompress_plane_rle and planar_decompress_plane_rle_only in libfreerdp/codec/planar.c verify that a control byte exists but do not verify that the source buffer contains the zero to fifteen raw bytes declared by that control byte. A malicious RDP server can send a truncated planar bitmap or surface update whose final control byte claims additional raw bytes, causing the decoder to read beyond pSrcData while processing a color plane. This can crash the client and may disclose adjacent memory. This issue is fixed in version 3.29.0.
