FreeRDP: Heap out-of-bounds write in RemoteFX (RFX) Cache Bitmap V3 decode
Vulnerability Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.1, FreeRDP clients launched with the non-default /cache:codec:rfx option pass desktop stride and height to RemoteFX decoding for Cache Bitmap V3 data while allocating bitmap->data only for the smaller DstWidth and DstHeight in gdi_Bitmap_Decompress, allowing a malicious RDP server to trigger a heap out-of-bounds write with attacker-controlled offset and content. This issue is fixed in version 3.27.1.

Vulnerability Title
FreeRDP 缓冲区错误漏洞
Vulnerability Description
FreeRDP是FreeRDP团队开源的一款开源的远程桌面协议(RDP)的实现。 FreeRDP 3.27.1之前版本存在缓冲区错误漏洞,该漏洞源于在使用非默认的/cache:codec:rfx选项启动客户端时,将桌面步幅和高度传递给RemoteFX解码,而仅在gdi_Bitmap_Decompress中为较小的DstWidth和DstHeight分配bitmap->data,可能导致恶意RDP服务器触发堆越界写入。
