______________________________________________________________________________
PROBLEM:       A vulnerability has been identified in the Distributed
               Computing Environment (DCE) security deamon (secd).
PLATFORM:      IRIX 5.3, 6.2, 6.3, and 6.4 if OSF/DCE has been installed.
DAMAGE:        Vulnerable to denial of service attacks.
SOLUTION:      Upgrade to OSF/DCE &DFS 1.1C or install patches.
______________________________________________________________________________
VULNERABILITY  Silicon Graphics Inc. has investigated the issue and recommends
ASSESSMENT:    the following steps for neutralizing the exposure. It is HIGHLY
               RECOMMENDED that these measures be implemented on ALL
               vulnerable SGI systems.

- ------------------------
- ---- Issue Specifics ---
- ------------------------

The Open Group has released an advisory via CERT concerning a buffer overflow
which has been discovered with Distributed Computing Environment (DCE)
security demon (secd) causing it core dump and no longer accept connections.

Silicon Graphic's implementation of OSF/DCE is vulnerable to this denial of
service attack.

Silicon Graphics Inc. has investigated the issue and recommends the
following steps for neutralizing the exposure.  It is HIGHLY RECOMMENDED
that these measures be implemented on ALL vulnerable SGI systems.

This issue will be corrected in future releases of Silicon Graphic's OSF/DCE
implementation.


- ---------------
- ---- Impact ---
- ---------------

Any Silicon Graphics System that has purchased OSF/DCE and installed it on
IRIX 5.3, 6.2, 6.3 or 6.4, is vulnerable to this denial of service attack.

The denial of service attack can be performed locally and remotely and without
the use of a local account on the system.

Information on the denial of service attack has been posted as a CERT Vendor
Bulletin from the Open Group and can be found at:

ftp://ftp.cert.org/pub/cert_bulletins/VB-97.12.opengroup


- -----------------
- ---- Solution ---
- -----------------

Upgrade to OSF/DCE & DFS 1.1C and install the following patches from the
December 1997 or later Recommended/Required Patch Set:

   NOTES

     1) Upgrade operating system.

     2) Patches 2679, 2681 and 2683 are for the U.S. domestic version of
        OSF/DCE & DFS 1.1C and are not available from the standard SGI patch
        sources because they include strong encryption which cannot be
exported
        outside of the United States without authorization.  All U.S.
customers
        who have purchased Silicon Graphic's U.S. domestic implementation of
        the OSF/DCE & DFS 1.1C should have received an SGI patch CD which
        contains these restricted patches. Please contact your U.S. SGI
support
        provider if you have not received this patch CD:

        SC4-DCEDOM-1.1C   DCE Domestic Security Module 1.1C Patch CD


Patches are available via anonymous FTP and your service/support provider.

The SGI anonymous FTP site is sgigate.sgi.com (204.94.209.1) or its
mirror, ftp.sgi.com.   Security information and patches can be found
in the ~ftp/security and ~ftp/patches directories, respectfully.
