The advisory
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.
Check your whole app
Dependencies are only half of it. Free and read-only: before you push, run npx shippable-dev scan localhost:3000 in your project folder, no account needed. For your live app, you prove it's yours with a one-line tag first.
