How to Fix GHSA-f67m-9j94-qv9j

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

hyper fixed: 0.14.12 
Upgrade hyper to 0.14.12
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 hyper

How to Check if You Are Affected

To determine whether your application is affected by GHSA-f67m-9j94-qv9j, inspect your project dependencies for Hyper:

inspect dependencies for hyper

Analyze the terminal output to locate any version of Hyper in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.14.12), 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 Hyper, 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

Affected versions of this crate called `mem::uninitialized()` in the HTTP1 parser to create values of type `httparse::Header` (from the `httparse` crate). This is unsound, since `Header` contains references and thus must be non-null. The flaw was corrected by avoiding the use of `mem::uninitialized()`, using `MaybeUninit` instead.
