RHEL 6 : krb5 (RHSA-2010:0863)

critical Nessus Plugin ID 50635

Synopsis

The remote Red Hat host is missing a security update for krb5.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0863 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL krb5 package based on the guidance in RHSA-2010:0863.
