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 reuses a cached XImage whose data pointer references a freed RDPGFX surface buffer, because gdi_DeleteSurface frees surface-&gt;data without invalidating the appWindow-&gt;image that aliases it. Version 3.23.0 fixes the issue.
