CVE-2014-5354: plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1...

plugins/kdb/ldap/libkdb_ldap/ldap_principal2.c in MIT Kerberos 5 (aka krb5) 1.12.x and 1.13.x before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by creating a database entry for a keyless principal, as demonstrated by a kadmin "add_principal -nokey" or "purgekeys -all" command.

Security readout for executives and security teams

This flaw can let an authenticated Kerberos administrator or similarly privileged user crash a vulnerable MIT Kerberos KDC when LDAP backs the Kerberos database. The business impact is authentication disruption, not confirmed data theft. Exposure is narrow: affected versions are krb5 1.12.x and 1.13.x before 1.13.1 with LDAP KDC storage. Likely exposed systems are MIT Kerberos KDCs running krb5 1.12.x or 1.13.x before 1.13.1 and using LDAP as the KDC database backend. Standard file-backed KDC deployments are not identified in the source bundle as affected. Treat this as a targeted availability risk for Kerberos infrastructure. Patch vulnerable LDAP-backed KDCs during the next security maintenance window, faster if many administrators or delegated systems can modify principals. Mitigation focus: Apply vendor krb5 security updates or upgrade to a fixed release such as 1.13.1 or later.; Prioritize KDCs using the LDAP Kerberos database backend.; Restrict administrative permissions for principal creation and key removal operations..
