The update to the above referenced information is that SGI now has a

vulnerabilities.  See below for information on where to obtain the new
version.

SGI 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.

6.5.20 and in the version that is now downloadable.  See below.

Please note that this version of Apache will not be supported on IRIX
versions prior to 6.5.14.
