Synopsis :

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

Description :

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 RHSA-2002:250

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 distribution.

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