CyberRota Analysis
AI-GeneratedVersions of xrdp prior to 0.10.6.1 are vulnerable to a critical heap-based buffer overflow due to inadequate bounds checking when processing color map messages from a VNC server. An attacker can exploit this vulnerability to execute arbitrary code or cause a denial of service before authentication. Organizations using affected versions should prioritize patching to mitigate the risk of exploitation.

Original NVD 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.
