How to Fix GHSA-h3mf-4fwp-59c7

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

nalgebra fixed: 0.27.0
Upgrade nalgebra to 0.27.0
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 nalgebra

How to Check if You Are Affected

To determine whether your application is affected by GHSA-h3mf-4fwp-59c7, inspect your project dependencies for Nalgebra:

inspect dependencies for nalgebra

Analyze the terminal output to locate any version of Nalgebra in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.27.0), 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 General Security Weakness. In Nalgebra, 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 `Deserialize` implementation for `VecStorage` did not maintain the invariant that the number of elements must equal `nrows * ncols`. Deserialization of specially crafted inputs could allow memory access beyond allocation of the vector. This flaw was introduced in v0.11.0 ([`086e6e`](https://github.com/dimforge/nalgebra/commit/086e6e719f53fecba6dadad2e953a487976387f5)) due to the addition of an automatically derived implementation of `Deserialize` for `MatrixVec`. `MatrixVec` was later renamed to `VecStorage` in v0.16.13 ([`0f66403`](https://github.com/dimforge/nalgebra/commit/0f66403cbbe9eeac15cedd8a906c0d6a3d8841f2)) and continued to use the automatically derived implementation of `Deserialize`. This flaw was corrected in commit [`5bff536`](https://github.com/dimforge/nalgebra/commit/5bff5368bf38ddfa31416e4ae9897b163031a513) by returning an error during deserialization if the number of elements does not exactly match the expected size.
