CVE-2026-23530

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.21.0,freerdpbitmapdecompressplanar does not validate nSrcWidth/nSrcHeight against planar-maxWidth/maxHeight before RLE decode. A malicious server can trigger a client‑side heap buffer overflow, causing a crash DoS...
