NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp-server package and not the freerdp-server package as distributed by RHEL.

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.
