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 checksum validation flaws were discovered in the MIT Kerberosimplementation. A remote attacker could use these flaws to tamper withcertain Kerberos protocol packets and, possibly, bypass authentication orauthorization mechanisms and escalate their privileges. (CVE-2010-1323,CVE-2010-1324, CVE-2010-4020)Red Hat would like to thank the MIT Kerberos Team for reporting theseissues.This update also fixes the following bug:All krb5 users should upgrade to these updated packages, which containbackported patches to correct these issues. After installing the updatedpackages, the krb5kdc daemon will be restarted automatically.
