unsupported by SGI, but is available for free at the normal security
patch distribution site:

neutralizing the exposure.  It is HIGHLY RECOMMENDED that these measures
be implemented on ALL vulnerable SGI systems.

The most current version of the NQE package that was sold by SGI is  This version is subject to the vulnerabilities described above.

As of November 2001, NQE has been classified as a "Retired" product and
is not currently available from SGI.  NQE is still supported by SGI, but
it is no longer under development by SGI Engineering, and there will be
no further patches or fixes for it.

These products have been retired, and SGI will not be providing
a patch for these vulnerabilities.  SGI's recommendation is to
uninstall the product.

To determine if the product is installed, run the following command:

   # versions -b | grep NQE

If the output returned by the command looks similar to this:

   I  NQE33015_Client_only 10/28/1999  N Q E Client only
   I  NQE33015_Components_and_Client  10/28/1999  N Q E Components

...then NQE is installed and the system is vulnerable.

To uninstall the product, run the following command:

   # versions remove NQE*
