  "summary": "CVE-2026-41252 is fixed in xrdp on 1 platform, first by DEBIAN-CVE-2026-41252, released August 1, 2026. It is not reported as exploited. Patch Radar priority: Urgent.",
  "title": "xrdp: xrdp is an open source RDP server",
  "description": "xrdp is an open source RDP server. Versions 0.10.6 and prior contain a missing bounds check in xrdp, which allows a heap-based buffer overflow when operating in vnc-any mode. The issue occurs during the handling of RFB protocol color map messages from a VNC server, where incoming color indices are not properly validated. A malicious VNC server can exploit this flaw by sending crafted messages with out-of-range values, leading to an out-of-bounds write on the heap. This memory corruption can result in a denial of service (DoS) or potentially allow remote code execution (RCE) prior to authentication. This issue has been fixed in version 0.10.6.1.",
