Name of the Vulnerable Software and Affected Versions
FreeRDP versions prior to 3.32.2
Description
A use-after-free issue exists where malicious RDP servers can corrupt client memory. This occurs when the RDPGFX ResetGraphics handler is raced against the planar bitmap decoder. By sending ResetGraphics concurrently with compressed bitmaps of 32 bpp (bits per pixel) or more, an attacker can trigger a heap use-after-free or out-of-bounds read/write on shared planar buffers.
Recommendations
Update to version 3.32.2 or later.
