A malicious RDP server can offer a grayscale JPEG via clipboard redirection, corrupting client memory and crashing it when the item is pasted as CF_DIB bitmap data.","categories":["Unclassified"],"product":"FreeRDP","vendor":"FreeRDP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-110839","source_modified_at":"2026-10-15T15:33:06.233Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FreeRDP","vendor":"FreeRDP","versions":[{"version":"3.3.0","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-2026-110839","source_modified_at":"2026-10-15T15:33:06.233Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"FreeRDP","ecosystem":null},"version":"3.32.0","basis":"first unaffected version stated in the CVE record"}],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00221,"percentile":0.12035,"score_date":"2026-10-23"},"published_at":"2026-10-14T22:52:14.540Z","modified_at":"2026-10-15T15:33:06.233Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-110839","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T15:33:06.233Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-110839","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-99p4-8j24-wvj4","tags":["exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/freerdp-3.3.0-before-3.32.0-heap-out-of-bounds-write-via-grayscale-jpeg-clipboard-data","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":"2026-10-15T15:32:10.467016Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T15:33:06.233Z","content_hash":"02ac6882907b48e25be8dd0e0d213165e445d620307096952503982005618aee"}}
