Sun(sm) Alert Notification
     * Sun Alert ID: 102322
     * Synopsis: Security Vulnerability With Sun N1 Grid Engine Daemons
     * Category: Security
     * Product: Sun N1 Grid Engine 6, Sun Grid Engine 5.3
     * BugIDs: 6398008, 6397987, 6365380
     * Avoidance: Patch
     * State: Resolved
     * Date Released: 28-Jul-2006
     * Date Closed: 28-Jul-2006
     * Date Modified: 

1. Impact

   A security vulnerability in the Sun N1 Grid Engine daemons may allow
   local unprivileged users to kill either the qmaster or execd process
   and shutdown the grid service, creating a Denial of Service (DoS)
   condition. In certain cases, buffer overflows may be exploited by
   unprivileged local users to gain elevated privileges.

2. Contributing Factors

   This issue can occur in the following releases:

   SPARC Platform
     * Sun Grid Engine 5.3 (32-bit Solaris)
     * Sun Grid Engine 5.3 (64-bit Solaris)
     * Sun Grid Engine 5.3 (32-bit Solaris) NON-Solaris Package format
     * Sun Grid Engine 5.3 (64-bit Solaris) NON-Solaris Package format
     * N1 Grid Engine 6.0 (32-bit Solaris) without patch 123037-01
     * N1 Grid Engine 6.0 (64-bit Solaris) without patch 123038-01
     * N1 Grid Engine 6.0 (32-bit Solaris) NON-Solaris Package format
       without patch 123041-01
     * N1 Grid Engine 6.0 (64-bit Solaris) NON-Solaris Package format
       without patch 123042-01

   x86 Platform
     * Sun Grid Engine 5.3
     * Sun Grid Engine 5.3 NON-Solaris Package format
     * N1 Grid Engine 6.0 without patch 123039-01
     * N1 Grid Engine 6.0 NON-Solaris Package format without patch
       123043-01
     * N1 Grid Engine 6.0 (x64) without patch 123040-01
     * N1 Grid Engine 6.0 (x64) NON-Solaris Package format without patch
       123044-01

   Linux
     * Sun Grid Engine 5.3
     * N1 Grid Engine 6.0 without patch 123045-01
     * N1 Grid Engine 6.0 (x64) without patch 123046-01

   Windows
     * N1 Grid Engine 6.0 without patch 123052-01

   HP-UX
     * N1 Grid Engine 6.0 without patch 123050-01

   AIX
     * N1 Grid Engine 6.0 (for AIX 4.3) without patch 123047-01
     * N1 Grid Engine 6.0 (for AIX 5.1) without patch 123048-01

   Mac OS
     * N1 Grid Engine 6.0 without patch 123049-01

   IRIX
     * N1 Grid Engine 6.0 (for IRIX 6.5) without patch 123051-01

3. Symptoms

   Should the described exploit occur, the 'qmaster' or 'execd' process
   is shut down and a core file will be created.

   To verify that your 'qmaster' or 'execd' process is not up and
   running, search in the process table with the 'ps' command for the
   process name "sge_qmaster" or "sge_execd". The following examples show
   a running qmaster:

   On Mac OS:
    $ ps ax | grep sge_qmaster
    526  ??  S     12:44.97 /gridware/sge/bin/darwin/sge_qmaster

   all other platforms (including Windows, when using Windows Services
   for UNIX):
    $ ps -ef | grep sge_qmaster
    sgeadmin 13001 1 0 Apr 24 ? 19:17 /gridware/sge/bin/sol-sparc64/sge_qmaster

   If no 'qmaster' or 'execd' process was found in the process table
   the cluster may be affeced by this issue. 

4. Relief/Workaround

   There is no workaround for this issue. Please see the Resolution
   section below.

5. Resolution

   This issue is addressed in the following releases:

   SPARC Platform

       later
     * N1 Grid Engine 6.0 (64-bit Solaris) with patch 123038-01 or
