A malicious RDP server can send a point-bearing polygon order followed by a zero-point order to crash a client with +async-update enabled.","categories":["Unclassified"],"product":"FreeRDP","vendor":"FreeRDP","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109943","source_modified_at":"2026-10-14T14:05:17.824Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"FreeRDP","vendor":"FreeRDP","versions":[{"version":"3.29.0","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-2026-109943","source_modified_at":"2026-10-14T14:05:17.824Z","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":0.0027,"percentile":0.18177,"score_date":"2026-10-23"},"published_at":"2026-10-13T13:27:11.928Z","modified_at":"2026-10-14T14:05:17.824Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109943","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-14T14:05:17.824Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-109943","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-pg3f-chj4-mrw6","tags":["vendor-advisory"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/freerdp-3.29.0-before-3.32.0-double-free-via-async-update-polygon-order","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":"2026-10-14T14:04:08.546668Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-14T14:05:17.824Z","content_hash":"a64a3f743f910d06199aa0f6ab1866c598be9083b337d7f0b3e32da921e9c3d8"}}
