A malicious RDP server can send a negative topLevelLeft to clients connecting with /video, causing an out-of-bounds write of decoded H.264 picture data or a client abort.","categories":["Unclassified"],"product":"FreeRDP","vendor":"FreeRDP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109251","source_modified_at":"2026-10-18T11:49:17.915Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"FreeRDP","vendor":"FreeRDP","versions":[{"version":"0","status":"affected","versionType":"semver","lessThan":"3.32.0"},{"version":"3.32.0","status":"unaffected","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109251","source_modified_at":"2026-10-18T11:49:17.915Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"FreeRDP","ecosystem":null},"version":"3.32.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00237,"percentile":0.13925,"score_date":"2026-10-23"},"published_at":"2026-10-12T16:04:24.223Z","modified_at":"2026-10-18T11:49:17.915Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109251","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T11:49:17.915Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109251","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-grvc-qhhp-7h6m","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/freerdp-before-3.32.0-out-of-bounds-write-via-ms-rdpegt-video-geometry","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-18T11:49:14.302896Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T11:49:17.915Z","content_hash":"2d2651c82d88b35f7f88af10ce20db8811458fce173ea12ca9363f4742f44cf1"}}
