How to Fix GHSA-c439-chv8-8g2j

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

os_socketaddr fixed: 0.2.2 
Upgrade os_socketaddr to 0.2.2
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 os_socketaddr

How to Check if You Are Affected

To determine whether your application is affected by GHSA-c439-chv8-8g2j, inspect your project dependencies for Os socketaddr:

inspect dependencies for os_socketaddr

Analyze the terminal output to locate any version of Os socketaddr in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.2), 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 Os socketaddr, 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 [`os_socketaddr`](https://crates.io/crates/os_socketaddr) crate has assumed `std::net::SocketAddrV4` and `std::net::SocketAddrV6` have the same memory layout as the system C representation `sockaddr`. It has simply casted the pointers to convert the socket addresses to the system representation. These layout were [changed into idiomatic rust types](https://github.com/rust-lang/rust/pull/78802) in nightly `std`. Starting from rustc 1.64 the affected versions of this crate will have undefined behaviour.
