Vulnerability Scan Summary
Check for the version of the krb packages

Detailed Explanation for this Vulnerability Test

Updated packages fix a vulnerability found in the Kerberos FTP client
distributed with the Red Hat Linux Advanced Server krb5 packages.

[Updated 06 Feb 2003]
Added fixed packages for Advanced Workstation 2.1. For Advanced
Workstation 2.1 these packages also fix CVE-2002-1235 as described in

Kerberos is a network authentication system.

A problem has been found in the Kerberos FTP client. When retrieving a
file with a name beginning with a pipe character, the FTP client will
pass the file name to the command shell in a system() call. This could
allow a malicious FTP server to write to files outside of the current
directory or execute commands as the user running the FTP client.

The Kerberos FTP client runs as the default FTP client when the Kerberos
package krb5-workstation is installed on a Red Hat Linux Advanced Server

All users of Kerberos are advised to upgrade to these errata packages which
contain a backported patch and are not vulnerable to this issue.
