Vulnerability Assessment Details

Fedora Core 3 2004-564: krb5

Vulnerability Assessment Summary
Check for the version of the krb5 package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory FEDORA-2004-564 (krb5).

Kerberos V5 is a trusted-third-party network authentication system,
which can improve your network's security by eliminating the insecure
practice of cleartext passwords.

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 permit 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 a possible hacker could create a
specially crafted temporary file that could permit 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.
