Upstream source description

In deployments using BoKS keytab management, affected versions of boks_keytabmd generate Active Directory service-account passwords from a predictable pseudo-random sequence seeded with the current Unix timestamp. An attacker who knows the service principal and can estimate the password-change time can reproduce a limited candidate set and verify candidates offline.
