Test ID:1.3.6.1.4.1.25623.1.0.63761
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2009:0410
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2009:0410.

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 input validation flaw was found in the ASN.1 (Abstract Syntax Notation
One) decoder used by MIT Kerberos. A remote attacker could use this flaw to
crash a network service using the MIT Kerberos library, such as kadmind or
krb5kdc, by causing it to dereference or free an uninitialized pointer or,
possibly, execute arbitrary code with the privileges of the user running
the service. (CVE-2009-0846)

All krb5 users should upgrade to these updated packages, which contain a
backported patch to correct this issue. All running services using the MIT
Kerberos libraries must be restarted for the update to take effect.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
