CentOS Errata and Security Advisory CESA-2013:0748

Kerberos is a network authentication system which allows clients and servers to authenticate to each other using symmetric encryption and a trusted third-party, the Key Distribution Center (KDC).

A NULL pointer dereference flaw was found in the way the MIT Kerberos KDC processed certain TGS (Ticket-granting Server) requests. A remote, authenticated attacker could use this flaw to crash the KDC via a specially-crafted TGS request. (CVE-2013-1416)

All krb5 users should upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the updated packages, the krb5kdc daemon will be restarted automatically.

Merged security bulletin from advisories:

Affected packages: krb5 krb5-devel krb5-libs krb5-pkinit-openssl krb5-server krb5-server-ldap krb5-workstation
