  "details" : [ "FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0, a client-side heap buffer overflow occurs in the  FreeRDP client’s `gdi_SurfaceToSurface` path due to a mismatch between destination rectangle clamping and the actual copy size. A malicious server can trigger a client‑side heap buffer overflow, 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 malicious server can exploit a client-side heap buffer overflow vulnerability in the `gdi_SurfaceToSurface` path. This vulnerability, caused by a mismatch in memory handling, can lead to a crash (Denial of Service) of the client application. Furthermore, it carries a risk of heap corruption, which could potentially enable arbitrary code execution on the affected system." ],
  "statement" : "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.",
