NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp3 package and not the freerdp3 package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.23.0, rail_window_free dereferences a freed xfAppWindow pointer during HashTable_Free cleanup because xf_rail_window_common calls free(appWindow) on title allocation failure without first removing the entry from the railWindows hash table, leaving a dangling pointer that is freed again on disconnect. Version 3.23.0 fixes the vulnerability.
