Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-03.

Fixed in 0.10.6.1
Recommended fix High confidence

xrdp 0.10.6.1

  1. 1. Check the current installed version of xrdp by running: dpkg -l | grep xrdp or rpm -qa | grep xrdp
  2. 2. Update the package repository index: sudo apt update (Debian/Ubuntu) or sudo yum check-update (RHEL/CentOS)
  3. 3. Upgrade xrdp to version 0.10.6.1 or later: sudo apt install xrdp=0.10.6.1 (Debian/Ubuntu) or sudo yum update xrdp (RHEL/CentOS)
  4. 4. Alternatively, compile from source: Download xrdp version 0.10.6.1 from github.com/neutrinolabs/xrdp/releases
  5. 5. Restart the xrdp service: sudo systemctl restart xrdp
  6. 6. Verify the installed version matches 0.10.6.1 or later
