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.
Description:	Summary: The remote host is missing an update for the 'krb5' package(s) announced via the referenced advisory. Vulnerability Insight: 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. Affected Software/OS: 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) Solution: Please Install the Updated Packages. CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
