NVD Description

Note: Versions mentioned in the description apply to the upstream krb5 package. See Remediation section below for Debian:9 relevant versions.

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.

Remediation

Upgrade Debian:9 krb5 to version 1.12.1+dfsg-16 or higher.
