Samba 4.x < 4.8.12 / 4.9.x < 4.9.8 / 4.10.x < 4.10.3 Man in the Middle Vulnerability (CVE-2018-16860)

The version of Samba running on the remote host is 4.x prior to 4.8.12, 4.9.x prior to 4.9.8 or 4.10.x prior to 4.10.3. It is, therefore, affected by a man in the middle vulnerability in the Heimdal KDC due to an design error. An authenticated, remote attacker can exploit this, via replacing the...

Samba AD DC S4U2Self/S4U2Proxy unkeyed checksum

Description S4U2Self is an extension to Kerberos used in Active Directory to allow a service to request a kerberos ticket to itself from the Kerberos Key Distribution Center KDC for a non-Kerberos authenticated user principal in Kerboros parlance. This is useful to allow internal code paths to be...

Denial Of Service (DoS)

Kerberos is a networked authentication system which allows clients and servers to authenticate to each other with the help of a trusted third party, the Kerberos KDC. A memory leak flaw was found in the krb5unparsename function of the MIT Kerberos kadmind service. An authenticated attacker could...

Remote Code Execution

Kerberos is vulnerable to remote code execution RCE. If kadmind were used with an LDAP back end for the KDC database, a remote, authenticated attacker who has the permissions to set the password policy could crash kadmind by attempting to use a named ticket policy object as a password policy for ...

Debian DLA-1643-1 : krb5 security update

krb5, a MIT Kerberos implementation, had several flaws in LDAP DN checking, which could be used to circumvent a DN containership check by supplying special parameters to some calls. Further an attacker could crash the KDC by making S4U2Self requests. For Debian 8 'Jessie', these problems have bee...
