Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated Kerberos (krb5) packages that correct buffer overflow and
temporary file bugs are now available for Red Hat Enterprise Linux.

Kerberos is a networked authentication system that uses a trusted
third party (a KDC) to authenticate clients and servers to each other.

A heap based buffer overflow bug was found in the administration
library of Kerberos 1.3.5 and earlier. This bug could allow an
authenticated remote attacker to execute arbitrary commands on a
realm's master Kerberos KDC. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-1189 to this
issue.

Additionally a temporary file bug was found in the Kerberos
krb5-send-pr program. It is possible that an attacker could create a
temporary file that would allow an arbitrary file to be overwritten
which the victim has write access to. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-0971
to this issue.

All users of krb5 should upgrade to these updated packages, which
contain backported security patches to resolve these issues.
