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 . The Public Key Cryptography for Initial Authentication in Kerberos capability provides support for using public-key authentication with Kerberos. A double-free flaw was found in the way the MIT Kerberos KDC handled initial authentication requests , when the KDC was configured to provide the PKINIT capability. A remote attacker could use this flaw to cause the KDC daemon to abort by using a specially-crafted AS-REQ request. 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.
