______________________________________________________________________________
PROBLEM: A problem with SGI rpc.statd program.
PLATFORM: All SGI systems running IRIX 3.x, 4.x, 5.x, and 6.x.
DAMAGE: The vulnerabilities found within the rpc.statd program could be
used in several ways including removal of files and denial of
service attacks.
SOLUTION: Upgrade and/or install patch depending on source distributions.
______________________________________________________________________________
VULNERABILITY Knowledge of how to exploit this vulnerability is becoming
ASSESSMENT: widely known.
______________________________________________________________________________
CIAC has obtained information from SGI describing a vulnerability in the
rpc.statd program. If you are currently running IRIX 3.x, 4.x, 5.x, and 6.x,
you should install the proper patch.

It has been found that there are some security vulnerabilities within the
/usr/etc/rpc.statd program. After further investigation, SGI recommends
the following steps for neutralizing this possible means of exploit. It
is HIGHLY RECOMMENDED that these measures be done on ALL SGI systems
running IRIX 3.x, 4.x, 5.x and 6.x. The issue will be permanently
corrected in a future release of IRIX.

**** IRIX 3.x ****
Silicon Graphics Inc, no longer supports the IRIX 3.x operating system
and therefore has no patches or binaries to provide.
If possible, it is recommended that the system be upgrade to a
supported version of IRIX (see below) and then install the patch
for that particular IRIX version.
**** IRIX 4.x ****
As of the date of this document, SGI does not have a IRIX 4.x binary
replacement that addresses this particular issue. If in the future,
a replacement binary is generated, additional advisory information will
be provided.
If possible, it is recommended that the system be upgrade to a
supported version of IRIX (see below) and then install the patch
for that particular IRIX version.
**** IRIX 5.0.x, 5.1.x ****
For the IRIX operating systems versions 5.0.x and 5.1.x, an upgrade
to 5.2 or better is required first. When the upgrade is completed,
then the patches described in the following sections can be applied
depending on the final version of the upgrade.
**** IRIX 5.2 ****
For the IRIX operating system version 5.2, an inst-able patch has been
generated and made available via anonymous FTP and your service/support
provider. The patch is number 1145 and will install on IRIX 5.2 only.
The SGI anonymous FTP site is sgigate.sgi.com (204.94.209.1) or its
mirror, ftp.sgi.com. Patch 1145 can be found in the following
directories on the FTP server:
~ftp/Security
or
~ftp/Patches/5.2
