Описание
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, xf_Pointer_New frees cursorPixels on failure, then pointer_free calls xf_Pointer_Free and frees it again, triggering ASan UAF. A malicious server can trigger a client‑side use after free, causing a crash (DoS) and potential heap corruption with code‑execution risk depending on allocator behavior and surrounding heap layout. Version 3.21.0 contains a patch for the issue.
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A malicious server can exploit a use-after-free vulnerability by enticing a client to connect to it. This can lead to a client-side crash, resulting in a Denial of Service (DoS), and potentially allow for arbitrary code execution due to heap corruption.
Отчет
For this vulnerability to be exploited, a client must connect to a maliciously-configured server. Red Hat recommends that FreeRDP clients are only used to connect to trusted servers.
