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).
Multiple checksum validation flaws were discovered in the MIT Kerberos
implementation. A remote attacker could use these flaws to tamper with
certain Kerberos protocol packets and, possibly, bypass authentication or
authorization 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 these
issues.
This update also fixes the following bug:
All krb5 users should upgrade to these updated packages, which contain
backported patches to correct these issues. After installing the updated
packages, the krb5kdc daemon will be restarted automatically.
