Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.23.0

Description FreeRDP is a free implementation of the Remote Desktop Protocol. A previous fix for a heap-use-after-free issue was incomplete. The vulnerable code exists in the SDL2 implementation, where a pointer is not nulled after being freed, potentially leading to a security issue. The fix was initially applied only to the SDL3 code path.

Recommendations Update to version 3.23.0 or later.
