SGI Security Advisory 20030801-01-P - It is possible to create a Denial of Service attack on the IRIX nfsd through the use of carefully crafted packets which cause XDR decoding errors. This can lead to kernel panicing the system. No local account or access to an NFS mount point is required, so this could be constructed as a remote exploit.

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

It's been reported that it is possible to create a Denial of Service attack
on the IRIX nfsd through the use of carefully crafted packets which cause
XDR decoding errors. This can lead to kernel panicing the system.  No local account or access to an NFS mount point is required, so this could be constructed as a remote exploit.

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.

These issues have been corrected with patches and in future releases of IRIX.


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

nfs is installed by default on IRIX 6.5 systems.

To determine the version of IRIX you are running, execute the following
command:

  # /bin/uname -R

That will return a result similar to the following:

  # 6.5 6.5.19f

The first number ("6.5") is the release name, the second ("6.5.16f" in this
case) is the extended release name.  The extended release name is the
"version" we refer to throughout this document.

To see if nfs is installed, execute the following command:

$ versions -b | grep nfs
I  nfs                  05/15/2003  Network File System, 6.5.20f


- ----------------------------
- --- Temporary Workaround ---
- ----------------------------

There is no effective workaround available for these problems.  SGI
recommends either upgrading to IRIX 6.5.20, or installing the appropriate
patch from the listing below.


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

SGI has provided a series of patches for these vulnerabilities. Our
recommendation is to upgrade to IRIX 6.5.20, or install the appropriate
patch.
