Test ID:1.3.6.1.4.1.25623.1.0.68546
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0926
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0926.

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)

Red Hat would like to thank the MIT Kerberos Team for reporting these
issues.

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.

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
