Description

Kerberos is a network authentication system which allows clients andservers to authenticate to each other using symmetric encryption and atrusted third-party, the Key Distribution Center (KDC).Multiple NULL pointer dereference and assertion failure flaws were foundin the MIT Kerberos KDC when it was configured to use an LDAP (LightweightDirectory Access Protocol) or Berkeley Database (Berkeley DB) back end. Aremote attacker could use these flaws to crash the KDC. (CVE-2011-1527,CVE-2011-1528, CVE-2011-1529)Red Hat would like to thank the MIT Kerberos project for reporting theCVE-2011-1527 issue. Upstream acknowledges Andrej Ota as the originalreporter of CVE-2011-1527.All krb5 users should upgrade to these updated packages, which contain abackported patch to correct these issues. After installing the updatedpackages, the krb5kdc daemon will be restarted automatically.
