Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.24.0

Description FreeRDP is a free implementation of the Remote Desktop Protocol. A client-side heap out-of-bounds read/write issue exists in FreeRDP's bitmap cache subsystem. This is due to an incorrect boundary check in the bitmap cache put function when handling a CACHE BITMAP ORDER (Rev1) message with a cacheId equal to maxCells. This allows a malicious server to bypass security checks and access memory outside the allocated array.

Recommendations Update to version 3.24.0 or later.
