| Doc Text: |
A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This use-after-free vulnerability occurs because the `xf_AppUpdateWindowFromSurface` function reuses a cached image whose data pointer references a freed RDPGFX surface buffer. A remote attacker could exploit this flaw, potentially leading to a denial of service (DoS) condition.
