SUSE CVE-2015-2694

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,...

krb5: issues in OTP and PKINIT kdcpreauth modules leading to requires_preauth bypass

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 dictionary attack...

lib32-krb5: multiple issues

CVE-2014-5355 denial of service When a server process uses the krb5recvauth function, an unauthenticated remote attacker can cause a NULL dereference by sending a zero-byte version string, or a read beyond the end of allocated storage by sending a non-null-terminated version string. The example...

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 ...
