CyberRota Analysis
AI-GeneratedFreeRDP clients prior to version 3.27.1 are vulnerable to a heap out-of-bounds write due to improper handling of bitmap data when using the non-default /cache:codec:rfx option. This vulnerability allows a malicious RDP server to exploit the flaw, potentially leading to arbitrary code execution or system compromise. Organizations utilizing FreeRDP for remote desktop connections should prioritize upgrading to the latest version to mitigate this high-severity risk.

Original NVD 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.
