How to fix?

Upgrade calamine to version 0.17.0 or higher.

Overview

calamine is an Excel/OpenDocument Spreadsheets file reader/deserializer, in pure Rust.

Affected versions of this package are vulnerable to Out-of-bounds Write which allows attackers to overwrite heap-memory locations. This is because Vec::set_len is used without proper memory claiming, and this uninitialized memory is used for a user-provided Read operation, as demonstrated by Sectors::get.
