Description:Summary:
The remote host is missing an update for the 'krb5'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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).

An invalid free flaw was found in the password-changing capability of the
MIT Kerberos administration daemon, kadmind. A remote, unauthenticated
attacker could use this flaw to cause kadmind to abort via a
specially-crafted request. (CVE-2011-0285)

All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct this issue. After installing the updated
packages, the kadmind daemon will be restarted automatically.

Affected Software/OS:
krb5 on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
