Vulnerability from github – Published: 2022-01-07 00:09 – Updated: 2024-09-26 14:21

Summary

NumPy Buffer Overflow (Disputed)

Details

NOTE: The vendor does not agree this is a vulnerability; In (very limited) circumstances a user may be able provoke the buffer overflow, the user is most likely already privileged to at least provoke denial of service by exhausting memory. Triggering this further requires the use of uncommon API (complicated structured dtypes), which is very unlikely to be available to an unprivileged user.
