CVE-2026-35001: Integer Overflow or Wraparound in OpenS100 Project OpenS100
Description
CVE-2026-35001 is an integer overflow vulnerability in the OpenS100 project's S-102 Bathymetric Surface parser. It arises from unvalidated multiplication of grid dimension metadata values, leading to a 32-bit integer wraparound. This causes an undersized heap buffer allocation and subsequent out-of-bounds writes. Exploitation can result in application crashes or arbitrary code execution. The vulnerability affects version 0 of OpenS100. The CVSS 4.0 score is 8.4, indicating high severity.

Technical Analysis
OpenS100 through commit daa35b contains an integer overflow vulnerability in the S-102 Bathymetric Surface parser. Remote attackers can exploit the unvalidated multiplication of numPointsLatitudinal and numPointsLongitudinal in the S102_VG_BathymetryCoverage::Read() function, triggering a 32-bit integer wraparound. This leads to undersized heap buffer allocation and out-of-bounds writes when opening a crafted S-102 HDF5 file with malicious grid dimension metadata. The impact includes application crash or arbitrary code execution.
Potential Impact
Successful exploitation allows remote attackers to cause heap-based buffer overflows, potentially leading to application crashes or arbitrary code execution. This can compromise the affected system's integrity and availability.
