|Title:||RedHat Update for krb5 RHSA-2013:0942-01|
|Summary:||The remote host is missing an update for the 'krb5'; package(s) announced via the referenced advisory.|
The remote host is missing an update for the 'krb5'
package(s) announced via the referenced 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).
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.
krb5 on Red Hat Enterprise Linux (v. 5 server),
Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)
Please Install the Updated Packages.
