-----BEGIN PGP SIGNED MESSAGE----- SGI Security Advisory Title: xfsmd vulnerability Number: 20020605-01-I Date: June 20, 2002 Reference: CAN-2002-0359 - --- Issue Specifics --- It's been reported that the /usr/etc/xfsmd daemon has security vulnerabilities which can lead to a remote root exploit. See http://www.lsd-pl.net/ for more information. 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. Since the xfsmserv product is being retired, SGI has no plans to fix the xfsmd security issue. - --- Impact --- The /usr/etc/xfsmd daemon is part of the optional eoe.sw.xfsmserv package, and is not installed by default on IRIX 6.5 systems. but if it is installed, it will run by default. To determine the version of IRIX you are running, execute the following command: # uname -R That will return a result similar to the following: # 6.5 6.5.15f The first number ("6.5") is the release name, the second ("6.5.15f" in this 77case) is the extended release name. The extended release name is the "version" we refer to throughout this document. To see if xfsmd is installed, execute the following command: # versions eoe.sw.xfsmserv I = Installed, R = Removed Name Date Description I eoe 08/28/2001 IRIX Execution Environment, 6.5.13f I eoe.sw 08/28/2001 IRIX Execution Environment Software I eoe.sw.xfsmserv 08/28/2001 XFSM Server Software If the output resembles the above, then the package is installed and the system is vulnerable. This vulnerability was assigned the following CVE: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0359 - --- Temporary Workaround --- There is no effective workaround available for these problems. SGI recommends either disabling or uninstalling the product. To disable the product from running, perform the following steps: # killall /usr/etc/xfsmd # vi /etc/inetd.conf Look for a line in inetd.conf that looks like this: sgi_xfsmd/1 stream rpc/tcp wait root ?/usr/etc/xfsmd xfsmd ...and comment it out by putting a "#" at the beginning of the line: #sgi_xfsmd/1 stream rpc/tcp wait root ?/usr/etc/xfsmd xfsmd ...or simply remove the line from the file. # killall -HUP inetd To remove the product from the system, perform the following command: # versions remove eoe.sw.xfsmserv - --- Solution --- SGI will not be providing a fix or patches for this issue, as the product is being retired. Our recommendation is to follow the instructions in the Temporary Workaround section above. OS Version Vulnerable?
