{"id":"CVE-2026-35001","state":"PUBLISHED","title":"OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow","description":"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.","publishedAt":"2026-10-13T01:39:03.514Z","updatedAt":"2026-10-15T14:56:56.412Z","severity":{"score":7.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["OpenS100 Project OpenS100"],"affected":[{"vendor":"OpenS100 Project","product":"OpenS100","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2b1dafc11332a0a68930c687bde57b2e41074342","versionType":"git"}],"repo":"https://github.com/S-100ExpertTeam/OpenS100"}],"references":["https://doi.org/10.3390/s26206448","https://www.vulncheck.com/advisories/opens100-s-102-parser-integer-overflow-heap-buffer-overflow"],"weaknesses":["CWE-190","CWE-122"],"ingestedAt":"2026-10-29T20:11:40.391Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/35xxx/CVE-2026-35001.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-35001","state":"PUBLISHED","datePublished":"2026-10-13T01:39:03.514Z","dateUpdated":"2026-10-15T14:56:56.412Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-03-31T20:40:15.617Z"},"containers":{"cna":{"title":"OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow","descriptions":[{"lang":"en","value":"OpenS100 through commit 2b1dafc contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser.
