How to Fix GHSA-j8cj-hw74-64jv

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

hivex fixed: 0.2.1 
Upgrade hivex to 0.2.1
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 hivex

How to Check if You Are Affected

To determine whether your application is affected by GHSA-j8cj-hw74-64jv, inspect your project dependencies for Hivex:

inspect dependencies for hivex

Analyze the terminal output to locate any version of Hivex in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.1), 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-415: Double Free, where the product calls free() twice on the same memory address. In Hivex, 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

`Drop` implementation for `Hive` did perform free, but so did `Hive::close`, which, at the end of the scope performed `Drop`, therefore triggering double-free. Additionally, function `Hive::from_handle` was not marked as unsafe, making it, in combination with `as_handle` easy to clone and trigger double-free in safe code or triggering UB when using invalid pointer.
