{"id":"CVE-2026-44178","state":"PUBLISHED","title":"xrdp: Channel Data Forwarding Fixed-Size Buffer Overflow","description":"xrdp is an open source RDP server. Versions 0.10.6 and prior contain a heap-based buffer overflow vulnerability within the virtual channel forwarding mechanism. When forwarding data from a remote client to the internal channel server, the xrdp process utilizes a fixed-size buffer without adequate bounds checking on the incoming payload. An authenticated remote attacker can exploit this flaw by sending a specially crafted virtual channel message that exceeds the buffer capacity, leading to heap memory corruption. This may result in a denial of service or the execution of arbitrary code with the privileges of the xrdp process. This issue has been fixed in version 0.10.6.1.","publishedAt":"2026-07-20T16:54:30.590Z","updatedAt":"2026-07-23T03:56:21.519Z","severity":{"score":8.8,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["neutrinolabs xrdp"],"affected":[{"vendor":"neutrinolabs","product":"xrdp","versions":[{"version":"< 0.10.6.1","status":"affected"}]}],"references":["https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-hh7r-2rmq-q4g4","https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.6.1"],"weaknesses":["CWE-122"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/44xxx/CVE-2026-44178.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-44178","state":"PUBLISHED","datePublished":"2026-07-20T16:54:30.590Z","dateUpdated":"2026-07-23T03:56:21.519Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-05T14:39:34.924Z"},"containers":{"cna":{"title":"xrdp: Channel Data Forwarding Fixed-Size Buffer Overflow","descriptions":[{"lang":"en","value":"xrdp is an open source RDP server.
