`root` appended to group listings
Affected versions append `root` to group listings, unless the correct listing has exactly 1024 groups. This affects both: - The supplementary groups of a user - The group access list of the current process If the caller uses this information for access control, this may lead to privilege escalation. This crate is not currently maintained, so a patched version is not available. Versions older than 0.8.0 do not contain the affected functions, so downgrading to them is a workaround. ## Recommended alternatives - [`uzers`](https://crates.io/crates/uzers) (an actively maintained fork of the `users` crate) - [`sysinfo`](https://crates.io/crates/sysinfo)
