"A heap based buffer overflow bug was found in the administration
library of Kerberos 1.3.5 and earlier. This overflow in the password
history handling code could allow an authenticated remote attacker to
execute 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 command. It is possible that an attacker could create a
specially crafted temporary file that could 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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
