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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":43,"depthScoreParts":{"impact":42.9,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
