- --- Issue Specifics ---
- -----------------------
It has been reported there are several security issues affecting
Network File Systems rpc.mountd running IRIX 6.5.25, 6.5.26 & 6.5.27.
The bugs addressed by these patches are:
* 934110 rpc.mountd allows excessive access rights for read-mostly exports
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0139
* 933849 rpc.mountd denies access to anonymous clients whose hostname is
not listed in DNS, NIS or /etc/hosts
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0138
SGI has investigated the issue and recommends the following steps for
resolving this issue. It is HIGHLY RECOMMENDED that these measures
be implemented on ALL vulnerable SGI systems.
- --------------
- --- Impact ---
- --------------
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 6.5.27m
The first number ("6.5") is the release name, the second ("6.5.27m" in
this case) is the extended release name. The extended release name is
the "version" we refer to throughout this document.
- ----------------
- --- Solution ---
- ----------------
SGI has provided a series of patches for these vulnerabilities
and recommends that all affected operating systems install the
appropriate patch.
