Medium: krb5

Issue Overview: A flaw was found in the OTP kdcpreauth module of MIT Kerberos. A remote attacker could use this flaw to bypass the requirespreauth flag on a client principal and obtain a ciphertext encrypted in the principal's long-term key. This ciphertext could be used to conduct an off-line...

Design/Logic Flaw

The kdcpreauth modules in MIT Kerberos 5 aka krb5 1.12.x and 1.13.x before 1.13.2 do not properly track whether a client's request has been validated, which allows remote attackers to bypass an intended preauthentication requirement by providing 1 zero bytes of data or 2 an arbitrary realm name,...

CVE-2015-2694

MIT Kerberos 5 (krb5) 1.12.x and 1.13.x prior to 1.13.2 are vulnerable due to the kdcpreauth modules (OTP and PKINIT) not tracking client validation, enabling a remote attacker to bypass requires_preauth by submitting zero bytes or an arbitrary realm name. This can lead to obtaining a ciphertext ...
