{"id":"CVE-2026-41252","summary":"xrdp: lib_palette_update Heap Buffer Overflow & RCE","details":"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 are not properly validated. A malicious VNC server can exploit this flaw by sending crafted messages with out-of-range values, leading to an out-of-bounds write on the heap. This memory corruption can result in a denial of service (DoS) or potentially allow remote code execution (RCE) prior to authentication. This issue has been fixed in version 0.10.6.1.","aliases":["GHSA-w5vg-6qmv-j63j"],"modified":"2026-07-24T04:02:01.892495365Z","published":"2026-07-20T16:29:53.496Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-122"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/41xxx/CVE-2026-41252.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/2026/41xxx/CVE-2026-41252.json"},{"type":"ADVISORY","url":"https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-w5vg-6qmv-j63j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41252"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/neutrinolabs/xrdp","events":[{"introduced":"0"},{"fixed":"80c52879fead585d6347df5b3c587718adf8f5a5"}],"database_specific":{"cpe":"cpe:2.3:a:neutrinolabs:xrdp:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"0.10.6.1"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"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-2026-41252.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
