{"schema":"threatline.record/2","record":{"id":"CVE-2026-35001","aliases":[],"summary":"OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow","details":"OpenS100 through commit 2b1dafc contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser. An attacker can supply a crafted S-102 HDF5 file with malicious grid dimension metadata that causes memory corruption when a user opens it. In the S102_VG_BathymetryCoverage::Read() function, the numPointsLatitudinal and numPointsLongitudinal values are multiplied without validation, and the 32-bit result can wrap around, producing an undersized heap buffer allocation. Subsequent writes past the end of that buffer cause a heap-based buffer overflow, leading to an application crash or potential arbitrary code execution in the context of the user who opened the file.","categories":["Unclassified"],"product":"OpenS100","vendor":"OpenS100 Project","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-35001","source_modified_at":"2026-10-15T14:56:56.412Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"OpenS100","vendor":"OpenS100 Project","versions":[{"status":"affected","version":"0","lessThanOrEqual":"2b1dafc11332a0a68930c687bde57b2e41074342","versionType":"git"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00126,"percentile":0.02102,"score_date":"2026-10-23"},"published_at":"2026-10-13T01:39:03.514Z","modified_at":"2026-10-15T14:56:56.412Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-35001","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-15T14:56:56.412Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-35001","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://doi.org/10.3390/s26206448","tags":["technical-description","exploit"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/opens100-s-102-parser-integer-overflow-heap-buffer-overflow","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":"total","assessed_at":"2026-10-15T14:56:39.052989Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-15T14:56:56.412Z","content_hash":"a1e74e8e9b92b9c9926c9066cd7588be41e49cdcd1fe7f7bfdbdcfe5503d6ee1"}}
