RHSA-2010:0926-01: [RHSA-2010:0926-01] Moderate: krb5 security update

Product: Red Hat Enterprise Linux

Synopsis: Moderate: krb5 security update

3. Description: 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 mechanisms in certain configurations using Single-use Authentication Mechanisms. (CVE-2010-1323)

All krb5 users should upgrade to these updated packages, which contain a backported patch to correct these issues. After installing the updated packages, the krb5kdc daemon will be restarted automatically. Read more at www.criticalwatch.com
