CVE-2026-55238

xrdp is an open source RDP server. Versions 0.10.6 and prior contain a vulnerability concerning the processing of RDP Confirm Active PDU, where during the capability negotiation phase, the parser did not perform sufficient length validation for specific capability sets. A remote, unauthenticated...

CVE-2026-55238

CVE-2026-55238 affects xrdp prior to 0.10.6.1. The issue is in the RDP Confirm Active PDU capability negotiation: the parser did not validate lengths for certain capability sets, allowing a remote unauthenticated attacker to send malformed capability data. This can cause out-of-bounds memory read...

CVE-2026-44978

Summary: xrdp versions up to 0.10.6 contain a heap out-of-bounds read in the FIPS-specific receive paths when non-default security_layer and crypt_level are used. An unauthenticated remote attacker can trigger a denial-of-service by sending a crafted FIPS-protected PDU, via a non-default mode (se...

EUVD-2026-46017

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 ar...

CVE-2026-64621

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A double-free vulnerability exists when a FreeRDP client processes a specially crafted .rdp connection file. An attacker could convince a victim to open a malicious .rdp file, leading to a size-controlled...
