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