{"id":"UBUNTU-CVE-2026-35512","details":"xrdp is an open source RDP server. Versions through 0.10.5 have a heap-based buffer overflow in the EGFX (graphics dynamic virtual channel) implementation due to insufficient validation of client-controlled size parameters, allowing an out-of-bounds write via crafted PDUs. Pre-authentication exploitation can crash the process, while post-authentication exploitation may achieve remote code execution. This issue has been fixed in version 0.10.6. If users are unable to immediately update, they should run xrdp as a non-privileged user (default since 0.10.2) to limit the impact of successful exploitation.","modified":"2026-06-25T19:15:28.324117397Z","published":"2026-04-17T21:16:00Z","upstream":["CVE-2026-35512"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35512"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35512"},{"type":"REPORT","url":"https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-jg6p-7fg8-9hh6"}],"affected":[{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-infra-legacy%2Ftrusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.0-1","0.6.0-1ubuntu0.1","0.6.0-1ubuntu0.1+esm1","0.6.0-1ubuntu0.1+esm2","0.6.0-1ubuntu0.1+esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"xrdp","binary_version":"0.6.0-1ubuntu0.1+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.6.1-2","0.6.1-2ubuntu0.1","0.6.1-2ubuntu0.3","0.6.1-2ubuntu0.3+esm1","0.6.1-2ubuntu0.3+esm2","0.6.1-2ubuntu0.3+esm3"],"ecosystem_specific":{"binaries":[{"binary_version":"0.6.1-2ubuntu0.3+esm3","binary_name":"xrdp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-apps%2Fbionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.1-9","0.9.4-1","0.9.4-2","0.9.4-3","0.9.4-4","0.9.4-5","0.9.5-1","0.9.5-1build1","0.9.5-2","0.9.5-2ubuntu0.1~esm1","0.9.5-2ubuntu0.1~esm2","0.9.5-2ubuntu0.1~esm3"],"ecosystem_specific":{"binaries":[{"binary_name":"xorgxrdp","binary_version":"0.9.5-2ubuntu0.1~esm3"},{"binary_name":"xrdp","binary_version":"0.9.5-2ubuntu0.1~esm3"},{"binary_name":"xrdp-pulseaudio-installer","binary_version":"0.9.5-2ubuntu0.1~esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-apps%2Ffocal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.9-1","0.9.12-1","0.9.12-1ubuntu0.1","0.9.12-1ubuntu0.1+esm1","0.9.12-1ubuntu0.1+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"xrdp","binary_version":"0.9.12-1ubuntu0.1+esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.15-1ubuntu1","0.9.17-1","0.9.17-2","0.9.17-2ubuntu1","0.9.17-2ubuntu2","0.9.17-2ubuntu2+esm1","0.9.17-2ubuntu3","0.9.17-2ubuntu3+esm1","0.9.17-2ubuntu3+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"0.9.17-2ubuntu3+esm2","binary_name":"xrdp"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.21.1-1","0.9.24-2","0.9.24-3","0.9.24-3build1","0.9.24-3build2","0.9.24-4","0.9.24-4ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"xrdp","binary_version":"0.9.24-4ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.1-3","0.10.1-3.1","0.10.1-3.1+deb13u1build0.25.10.1"],"ecosystem_specific":{"binaries":[{"binary_name":"xrdp","binary_version":"0.10.1-3.1+deb13u1build0.25.10.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}},{"package":{"name":"xrdp","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/xrdp?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.10.1-3.1","0.10.1-4","0.10.1-4.1"],"ecosystem_specific":{"binaries":[{"binary_name":"xrdp","binary_version":"0.10.1-4.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35512.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/V
