   SYNOPSIS: Security Vulnerability in dtprintinfo
   DETAIL DESCRIPTION:

1. Impact

   A local user may be able to execute arbitrary code or commands with
   the privileges of the dtprintinfo(1) CDE Print Viewer. The
   dtprintinfo(1) CDE Print Viewer runs with root privileges.

   This issue can occur in the following releases:
   
   SPARC Platform
     * Solaris 2.6 without patch 106437-04

     * Solaris 8 without patch 110335-03
     * Solaris 9 without patch 114495-01
       
   x86 Platform
     * Solaris 2.6 without patch 106438-04
     * Solaris 7 without patch 107886-09
     * Solaris 8 without patch 110336-03
     * Solaris 9 without patch 114496-01
       
3. Symptoms

   There are no predictable symptoms that show this issue has been
   exploited.
   
   SOLUTION SUMMARY:
   
4. Relief/Workaround

   To work around the described issue, turn off the set-user-ID
   ("setuid") bit for dtprintinfo as root, shown below:
    # chmod 0555 /usr/dt/bin/dtprintinfo                                    

   This will cause dtprintinfo to lose the ability to display local print
   jobs.

     * Solaris 2.6 with patch 106437-04 or later
