How to Fix GHSA-9fjq-45qv-pcm7

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

ruint fixed: Latest secure release 
Upgrade ruint to Latest secure release
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 ruint

How to Check if You Are Affected

To determine whether your application is affected by GHSA-9fjq-45qv-pcm7, inspect your project dependencies for Ruint:

inspect dependencies for ruint

Analyze the terminal output to locate any version of Ruint in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer, where the product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. this may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data. In Ruint, 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

The function `reciprocal_mg10` is marked as safe but can trigger undefined behavior (out-of-bounds access) because it relies on `debug_assert!` for safety checks instead of `assert!`. When compiled in release mode, the `debug_assert!` is optimized out, potentially allowing invalid inputs to cause memory corruption.
