NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp package and not the freerdp package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, xf_rail_server_local_move_size dereferences a freed xfAppWindow pointer because xf_rail_get_window returns an unprotected pointer from the railWindows hash table, and the main thread can concurrently delete the window (via a window delete order) while the RAIL channel thread is still using the pointer. Version 3.23.0 fixes the issue.
