Short explanation

OpenS100 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.

Why does it matter?

This vulnerability can lead to out-of-bounds writes resulting in application crash or arbitrary code execution. The patch status could not be verified in the reviewed official sources.

What should be done?

Follow vendor advisories as patch status is unverified.

Show the technical text from the sources

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.
