CVE-2026-35001
OpenS100 S-102 Parser Integer Overflow Heap Buffer Overflow
HIGH 7.1EPSS 0.1%
OpenS100 through commit daa35b contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser that allows remote attackers to cause a heap-based buffer overflow by opening a crafted S-102 HDF5 file with malicious grid dimension metadata. Attackers can exploit the unvalidated multiplication of numPointsLatitudinal and numPointsLongitudinal values in the S102_VG_BathymetryCoverage::Read() function to trigger a 32-bit integer wraparound, resulting in undersized heap buffer allocation and subsequent out-of-bounds writes that lead to application crash or arbitrary code execution.
