RHSA-2013:0942 - Security Advisory
Synopsis
Moderate: krb5 security update
Type/Severity
Security Advisory: Moderate
Topic
Updated krb5 packages that fix one security issue are now available for
Red Hat Enterprise Linux 5 and 6.
The Red Hat Security Response Team has rated this update as having moderate
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.
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).
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)
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 and kadmind daemons will be restarted automatically.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
