I assume this should be either < 0.8.0 or < 0.7.0, use one of those instead.

```

# `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.

If using an older version is a defense, report that as a workaround

Versions older than 0.7.0 are not affected, so downgrading to them is a workaround.
