Sun(sm) Alert Notification

     * Sun Alert ID: 52111
     * Synopsis: On Solaris 9 a Security Issue with the newtask(1)

     * Category: Security
     * Product: Solaris
     * BugIDs: 4798119
     * Avoidance: Patch

1. Impact

   A local unprivileged user may be able to gain unauthorized root access
   due to a security issue with the newtask(1) command in Solaris 9.
   
2. Contributing Factors

   This issue can occur in the following releases:
   
   SPARC Platform
     * Solaris 9 without patch 114713-01
       
   x86 Platform
     * Solaris 9 without patch 114714-01
       
   Notes: Solaris 2.6 and 7 do not have the newtask(1) command and are
   therefore not affected by this issue.
   
   Solaris 8 is not affected by this issue.
   
3. Symptoms

   There are no predictable symptoms that would show the described
   problem has been exploited to gain root privileges.
   SOLUTION SUMMARY:
   
4. Relief/Workaround

   To work around the described issue, remove the setuid bit from
   newtask(1):
        # chmod u-s /usr/bin/sparcv7/newtask
        # chmod u-s /usr/bin/sparcv9/newtask 
        # chmod u-s /usr/bin/i86/newtask                       

   Note: removing the set-user-ID bit from the "newtask" binary will
   prevent unprivileged users from using the "newtask" command.
   
5. Resolution

   This issue is addressed in the following releases:
   
   SPARC Platform
     * Solaris 9 with patch 114713-01 or later
