users may append `root` 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.
