The remote Red Hat host is missing one or more security updates.
Updated krb5 packages that fix one security issue are now available
for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
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 uninitialized pointer use flaw was found in the way the MIT
Kerberos KDC handled TGS (Ticket-granting Server) request messages. A
remote, authenticated attacker could use this flaw to crash the KDC
or, possibly, disclose KDC memory or execute arbitrary code with the
privileges of the KDC (krb5kdc). (CVE-2010-1322)
Red Hat would like to thank the MIT Kerberos Team for reporting this
issue. Upstream acknowledges Mike Roszkowski as the original reporter.
All krb5 users should upgrade to these updated packages, which contain
a backported patch to correct this issue. After installing the updated
packages, the krb5kdc daemon will be restarted automatically.
