概要
FreeRDP has heap-use-after-free in xf_AppUpdateWindowFromSurface (freed appWindow)
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
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.
