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_AppUpdateWindowFromSurface reads from a freed xfAppWindow because the RDPGFX DVC thread obtains a bare pointer via xf_rail_get_window without any lifetime protection, while the main thread can concurrently delete the window through a fastpath window-delete order. Version 3.23.0 fixes the issue.
