Access to the font glyphs in xrdp_painter.c is not bounds-checked . Since some of this data is controllable by the user, this can result in an out-of-bounds read within the xrdp executable. The vulnerability allows an out-of-bounds read within a potentially privileged process. On non-Debian platforms, xrdp tends to run as root. Potentially an out-of-bounds write can follow the out-of-bounds read. There is no denial-of-service impact, providing xrdp is running in forking mode. This issue has been addressed in release 0.9.23.1. Users are advised to upgrade. There are no known workarounds for this vulnerability."}],"source":{"advisory":"GHSA-2hjx-rm4f-r9hw","discovery":"UNKNOWN"}},"adp":[{"title":"CVE Program Container","references":[{"name":"https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-2hjx-rm4f-r9hw","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/neutrinolabs/xrdp/security/advisories/GHSA-2hjx-rm4f-r9hw"},{"name":"https://github.com/neutrinolabs/xrdp/commit/73acbe1f7957c65122b00de4d6f57a8d0d257c40","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/neutrinolabs/xrdp/commit/73acbe1f7957c65122b00de4d6f57a8d0d257c40"},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/PFGL22QQF65OIZRMCKUZCVJQCKGUBRYE/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/RTXODUR4ILM7ZPA6ZGY6VSK4BBSBMKGY/","tags":["x_transferred"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/5FPGA4M7IYCP7OILDF2ZJEVSXUOFEFQ6/","tags":["x_transferred"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/05/msg00018.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T19:28:19.810Z"}},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-09-23T14:30:39.121571Z","id":"CVE-2023-42822","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-23T15:05:24.827Z"}}]}}
