CVE description: Authd, through version 0.3.6, did not sufficiently randomize user IDs to prevent collisions. A local attacker who can register user names could spoof another user's ID and gain their privileges. ----- original report ----- # Cause authd assigns user IDs as a pure function of the user name. Moreover, the set of UIDs is much too small for pseudo-random assignment to work: the birthday bound predicts random collisions will occur with probability 50% after only 54 562 IDs were assigned. `authd` only checks for uniqueness [within its local cache](https://github.com/ubuntu/authd/blob/4946962aa4ac6e5b7d2b53503026659581c73907/internal/users/cache/update.go#L67-L71), which - may be inconsistent across multiple systems within the same domain ; - may be purged, due to being stored in `/var/cache` ; - automatically removes entries of users who have not logged into that specific system within the last 6 months.
