How to Fix GHSA-2326-pfpj-vx3h

To remediate this vulnerability, upgrade all affected Lexical core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

lexical-core fixed: 1.0.0 
Upgrade lexical-core to 1.0.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for lexical-core

How to Check if You Are Affected

To determine whether your application is affected by GHSA-2326-pfpj-vx3h, inspect your project dependencies for Lexical core:

inspect dependencies for lexical-core

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Lexical core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

`RUSTSEC-2024-0377` contains multiple soundness issues: 1. [Bytes::read() allows creating instances of types with invalid bit patterns](https://github.com/Alexhuszagh/rust-lexical/issues/102) 1. [BytesIter::read() advances iterators out of bounds](https://github.com/Alexhuszagh/rust-lexical/issues/101) 1. [The `BytesIter` trait has safety invariants but is public and not marked `unsafe`](https://github.com/Alexhuszagh/rust-lexical/issues/104) 1. [`write_float()` calls `MaybeUninit::assume_init()` on uninitialized data, which is is not allowed by the Rust abstract machine](https://github.com/Alexhuszagh/rust-lexical/issues/95) 1. [`radix()` calls `MaybeUninit::assume_init()` on uninitialized data, which is is not allowed by the Rust abstract machine](https://github.com/Alexhuszagh/rust-lexical/issues/126) Version 1.0 fixes these issues, removes the vast majority of `unsafe` code, and also fixes some correctness issues.
