{"id":"CVE-2026-44178","summary":"xrdp: Channel Data Forwarding Fixed-Size Buffer Overflow","details":"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.","aliases":["GHSA-hh7r-2rmq-q4g4"],"modified":"2026-07-24T04:02:27.863880610Z","published":"2026-07-20T16:54:30.590Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-122"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44178.json"},"references":[{"type":"WEB","url":"https://github.com/neutrinolabs/xrdp/releases/tag/v0.10.6.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/44xxx/CVE-2026-44178.json"},{"type":"ADVISORY","url":"https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-hh7r-2rmq-q4g4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-44178"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/neutrinolabs/xrdp","events":[{"introduced":"0"},{"fixed":"80c52879fead585d6347df5b3c587718adf8f5a5"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:neutrinolabs:xrdp:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.10.6.1"}]}}],"versions":["v0.10.6.1-rc.1","v0.10.6","v0.10.5","v0.10.4.1","v0.10.4","v0.10.3","v0.10.2","v0.10.2-rc.1","v0.10.1","v0.10.0","v0.10.0-beta.3","v0.10.0-beta.2","v0.10.0-beta.1","v0.9.18","v0.9.17","v0.9.16","v0.9.15","v0.9.14","v0.9.13","v0.9.12","v0.9.11","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.4.rc1","v0.9.3","v0.9.3.rc1","v0.9.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-44178.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
