Scientific Linux Security Update : krb5 on SL5.x, SL6.x i386/x86_64 (20130612)

medium Nessus Plugin ID 66891

Language:

Synopsis

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

Description

It was found that kadmind's kpasswd service did not perform any validation on incoming network packets, causing it to reply to all requests. A remote attacker could use this flaw to send spoofed packets to a kpasswd service that appear to come from kadmind on a different server, causing the services to keep replying packets to each other, consuming network bandwidth and CPU. (CVE-2002-2443)

After installing the updated packages, the krb5kdc and kadmind daemons will be restarted automatically.

Solution

Update the affected packages.
