NVD Description

Note: Versions mentioned in the description apply only to the upstream krb5-server-ldap package and not the krb5-server-ldap package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The krb5_ldap_get_password_policy_from_dn function in plugins/kdb/ldap/libkdb_ldap/ldap_pwd_policy.c in MIT Kerberos 5 (aka krb5) before 1.13.1, when the KDC uses LDAP, allows remote authenticated users to cause a denial of service (daemon crash) via a successful LDAP query with no results, as demonstrated by using an incorrect object type for a password policy.
