{"id":"CVE-2026-35512","state":"PUBLISHED","title":"xrdp: Heap buffer overflow in EGFX channel","description":"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.","publishedAt":"2026-04-17T20:21:59.868Z","updatedAt":"2026-04-22T03:55:37.686Z","severity":{"score":8.7,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["neutrinolabs xrdp"],"affected":[{"vendor":"neutrinolabs","product":"xrdp","versions":[{"version":"< 0.10.6","status":"affected"}]}],"references":["https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-jg6p-7fg8-9hh6","https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.6"],"weaknesses":["CWE-122"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/35xxx/CVE-2026-35512.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-35512","state":"PUBLISHED","datePublished":"2026-04-17T20:21:59.868Z","dateUpdated":"2026-04-22T03:55:37.686Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-04-03T02:15:39.280Z"},"containers":{"cna":{"title":"xrdp: Heap buffer overflow in EGFX channel","descriptions":[{"lang":"en","value":"xrdp is an open source RDP server.
