github.com/juju/juju fixed: 0.0.0-20240829052008-43f0fc59790d 
Upgrade github.com/juju/juju to 0.0.0-20240829052008-43f0fc59790d
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 github.com/juju/juju

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-8038, inspect your project dependencies for Github.com/juju/juju:

inspect dependencies for github.com/juju/juju

Analyze the terminal output to locate any version of Github.com/juju/juju in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.0-20240829052008-43f0fc59790d), 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 Github.com/juju/juju, 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

### Impact An abstract UNIX domain socket responsible for introspection is available without authentication locally to any user with access to the network namespace where the local juju agent is running. On a juju controller agent, denial of service can be performed by using the `/leases/revoke` endpoint. Revoking leases in juju can cause availability issues. On a juju machine agent that is hosting units, disabling the unit component can be performed using the `/units` endpoint with a "stop" action. ### Patches Patch: https://github.com/juju/juju/commit/43f0fc59790d220a457d4d305f484f62be556d3b Patched in: - 3.5.4 - 3.4.6 - 3.3.7 - 3.1.10 - 2.9.51 ### Workarounds No workaround. ### References https://github.com/juju/juju/blob/725800953aaa29dbeda4f806097bf838e61644dd/worker/introspection/worker.go#L125
