1. Impact

A security vulnerability in the kcms_configure(1) command may allow local
unprivileged users the ability to modify any file on the system. This can
result in a Denial of Service (DoS) or possibly elevated privileges.

Note: kcms_configure is part of the Kodak Color Management System (KCMS)
which configures an X11 window system for use with the KCMS library.

This issue is described in CAN-2004-0481 (see:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0481)

     # chmod u-s /usr/openwin/bin/kcms_configure

The KCMS packages below could also be removed by using the pkgrm(1M)
command as root user:
