Hi

See

https://rustsec.org/advisories/RUSTSEC-2025-0132.html
https://github.com/advisories/GHSA-mj73-j457-8x9q
| maxminddb prior to version 0.27 declared Reader::open_mmap as safe
| despite wrapping an inherently unsafe memmap2 operation with no extra
| step done to guarantee safety. This could have led to undefined
| behaviour if the file were to be modified on disk while the memory map
| was still active.

Report:
https://github.com/oschwald/maxminddb-rust/issues/86
Fixed by: https://github.com/oschwald/maxminddb-rust/commit/98f0e4fff9678c841ed33f3b8a46322f6163c32a

Regards,
Salvatore
