Scientific Linux Security Update : krb5 on SL6.x i386/x86_64 (20120731)

high Nessus Plugin ID 61407
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

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 initial authentication requests (AS-REQ). A remote, unauthenticated attacker could use this flaw to crash the KDC via a specially crafted AS-REQ request. (CVE-2012-1015)

A NULL pointer dereference flaw was found in the MIT Kerberos administration daemon, kadmind. A Kerberos administrator who has the 'create' privilege could use this flaw to crash kadmind.
(CVE-2012-1013)

All krb5 users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the krb5kdc and kadmind daemons will be restarted automatically.

Solution

Update the affected packages.
