Description

MIT krb5 1.6 or later allows an authenticated kadmin with permission to add principals to an LDAP Kerberos database to circumvent a DN containership check by supplying both a "linkdn" and "containerdn" database argument, or by supplying a DN string which is a left extension of a container DN string but is not hierarchically within the container DN.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

5-1.6 ≤ v < 5-1.21.2
Affected range stops below 5-1.21.2, so it looks safe — our inference, not a vendor statement
