| Doc Text: |
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol (RDP). The `gdi_surface_bits()` function, which processes `SURFACE_BITS_COMMAND` messages, does not properly validate image dimensions (`bmp.width` and `bmp.height`) provided by a malicious RDP server. This can lead to a heap buffer overflow during bitmap decoding and memory operations. A remote attacker could exploit this to overwrite adjacent memory, potentially resulting in arbitrary code execution.
