Security Advisory Title: IRIX routed(1M) Vulnerability Number: 19981004-01-PX Date: October 21, 1998 ______________________________________________________________________________ Silicon Graphics provides this information freely to the SGI user community for its consideration, interpretation, implementation and use. Silicon Graphics recommends that this information be acted upon as soon as possible. Silicon Graphics provides the information in this Security Advisory on an "AS-IS" basis only, and disclaims all warranties with respect thereto, express, implied or otherwise, including, without limitation, any warranty of merchantability or fitness for a particular purpose.

A vulnerability has been discovered in routed(1M) which allows a malicious user to append debug and tracing information to arbitrary files on the system. Silicon Graphics Inc. 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. This issue has been corrected in future releases of IRIX. - --------------- - ---- Impact --- - --------------- The routed(1M) daemon is installed by default on IRIX. A local account is not needed in order to exploit this vulnerability. The vulnerability can be exploited remotely by using carefully crafted network packets. The vulnerability allows a malicious user to append routed(1M) debug tracing information to arbitrary files on the system. This vulnerability has been publicly discussed in Usenet newsgroups and mailing lists. - --------------------------- - ---- Temporary Solution --- - --------------------------- Although patches are available for this issue, it is realized that there may be situations where installing the patches immediately may not be possible. There are no workarounds for this routed(1M) vulnerability. The routed(1M) daemon must be disabled or patches installed. The steps below can be used to disable the routed(1M) daemon to prevent exploitation of this vulnerability until patches can be installed. ================= **** WARNING **** ================= Disabling routed(1M) daemon will prevent dynamic updates of the network routing tables. Static routes must be configured, see the route(1M) man page for more information. 1) Become the root user on the system. % /bin/su - Password: # 2) Verify routed(1M) daemon is enabled. # chkconfig Flag State ==== ===== routed on 3) Disable routed(1M) daemon. # chkconfig routed off 4) Verify routed(1M) daemon has been disabled. # chkconfig Flag State ==== ===== routed off 5) Stop and restart all system networking daemons. # /etc/init.d/network stop;/etc/init.d/network start 6) Return to previous user level. # exit % - ----------------- - ---- Solution --- - ----------------- OS Version Vulnerable?

There may be newer rollup patches that contain the security fix and are currently available from http://support.sgi.com/ or you SGI support provider. Patches are available via anonymous FTP and your service/support provider. The primary SGI anonymous FTP site for security information and patches is sgigate.sgi.com (204.94.209.1). Security information and patches can be found in the ~ftp/security and ~ftp/patches directories, respectively. For security and patch management reasons, ftp.sgi.com (mirror of sgigate) lags behind and does not do a real-time update of ~ftp/security and ~ftp/patches directories. ##### Patch File Checksums #### The actual patch will be a tar file containing the following files: Filename: README.patch.1638 Algorithm #1 (sum -r): 25810 10 README.patch.1638 Algorithm #2 (sum): 45994 10 README.patch.1638 MD5 checksum: 5CFFC234C3FD6A55AAF1724A23856464 Filename: patchSG0001638 Algorithm #1 (sum -r): 54461 3 patchSG0001638 Algorithm #2 (sum): 10118 3 patchSG0001638 MD5 checksum: 1A4F38FCB51AEA8444236CD0B78EE8BB Filename: patchSG0001638.eoe_hdr Algorithm #1 (sum -r): 10008 8 patchSG0001638.eoe_hdr Algorithm #2 (sum): 23343 8 patchSG0001638.eoe_hdr MD5 checksum: 960162CA99A3F2B00C1F2728F1FD82A8 Filename: patchSG0001638.eoe_man Algorithm #1 (sum -r): 25386 52 patchSG0001638.eoe_man Algorithm #2 (sum): 5077 52 patchSG0001638.eoe_man MD5 checksum: ECA70503EEB12265CB56CC1CBA0AAB74 Filename: patchSG0001638.eoe_sw Algorithm #1 (sum -r): 04406 241 patchSG0001638.eoe_sw Algorithm #2 (sum): 3325 241 patchSG0001638.eoe_sw MD5 checksum: 123CA06F9A5B91D1D56458FF455538C4 Filename: patchSG0001638.idb Algorithm #1 (sum -r): 18065 4 patchSG0001638.idb Algorithm #2 (sum): 22105 4 patchSG0001638.idb MD5 checksum: E8333BC62A89A6C4A2326F9C9089565A Algorithm #1 (sum -r): 59269 9 README.patch.2413 Algorithm #2 (sum): 61782 9 README.patch.2413 MD5 checksum: 81A1CC8326C35FC9D8A36E6E4C2ECE7E Filename: patchSG0002413 Algorithm #1 (sum -r): 35882 3 patchSG0002413 Algorithm #2 (sum): 14583 3 patchSG0002413 MD5 checksum: ADD49D668CDF3644CB80AEE1B5EC530F Filename: patchSG0002413.eoe_hdr Algorithm #1 (sum -r): 43690 8 patchSG0002413.eoe_hdr Algorithm #2 (sum): 23342 8 patchSG0002413.eoe_hdr MD5 checksum: B88588DEC32FB32AEB2F8420BC7E172E Filename: patchSG0002413.eoe_man Algorithm #1 (sum -r): 34349 39 patchSG0002413.eoe_man Algorithm #2 (sum): 52356 39 patchSG0002413.eoe_man MD5 checksum: 4CA92E9BDF2FD32354CE3F640B69BA75 Filename: patchSG0002413.eoe_sw Algorithm #1 (sum -r): 44812 216 patchSG0002413.eoe_sw Algorithm #2 (sum): 33076 216 patchSG0002413.eoe_sw MD5 checksum: 6CC82F0698061F49686FADCB7C27D97F Filename: patchSG0002413.idb Algorithm #1 (sum -r): 19469 3 patchSG0002413.idb Algorithm #2 (sum): 44128 3 patchSG0002413.idb MD5 checksum: F8B97D25D2C386CB3DF9C67940B39D7E Filename: README.patch.2770 Algorithm #1 (sum -r): 50674 54 README.patch.2770 Algorithm #2 (sum): 55165 54 README.patch.2770 MD5 checksum: AF52BE0D11D1ABA533F750808B7C6976 Filename: patchSG0002770 Algorithm #1 (sum -r): 45021 29 patchSG0002770 Algorithm #2 (sum): 38712 29 patchSG0002770 MD5 checksum: 8E458BF95BB806D5082D36F5C323C3AD Filename: patchSG0002770.dev_hdr Algorithm #1 (sum -r): 55046 18 patchSG0002770.dev_hdr Algorithm #2 (sum): 21666 18 patchSG0002770.dev_hdr MD5 checksum: 12D756C9AAADDA464F628FB08B8012C2 Filename: patchSG0002770.eoe1_man Algorithm #1 (sum -r): 58486 19 patchSG0002770.eoe1_man Algorithm #2 (sum): 19828 19 patchSG0002770.eoe1_man MD5 checksum: 971A700918352743FDFAD9DC7AAC7F08 Filename: patchSG0002770.eoe1_sw Algorithm #1 (sum -r): 19070 3874 patchSG0002770.eoe1_sw Algorithm #2 (sum): 2196 3874 patchSG0002770.eoe1_sw MD5 checksum: BAC859508D8025C05CF7EF8732E8C340 Filename: patchSG0002770.eoe2_man Algorithm #1 (sum -r): 20509 16 patchSG0002770.eoe2_man Algorithm #2 (sum): 64242 16 patchSG0002770.eoe2_man MD5 checksum: B0491FEFB0CE1C0BC03F7A1345BDE250 Filename: patchSG0002770.eoe2_sw Algorithm #1 (sum -r): 35898 1681 patchSG0002770.eoe2_sw Algorithm #2 (sum): 50094 1681 patchSG0002770.eoe2_sw MD5 checksum: 009D8A477E83CE4646F004FB3F48953E Filename: patchSG0002770.idb Algorithm #1 (sum -r): 46255 53 patchSG0002770.idb Algorithm #2 (sum): 6566 53 patchSG0002770.idb MD5 checksum: 8A53DCAFC6BF0E8A4682D74733834C18 Filename: patchSG0002770.nfs_man Algorithm #1 (sum -r): 22345 17 patchSG0002770.nfs_man Algorithm #2 (sum): 21111 17 patchSG0002770.nfs_man MD5 checksum: 8782FA52CAB650472352DABC1C38B823 Filename: patchSG0002770.nfs_sw Algorithm #1 (sum -r): 22859 162 patchSG0002770.nfs_sw Algorithm #2 (sum): 7001 162 patchSG0002770.nfs_sw MD5 checksum: BA848F9526D84CF205C7DD080CF7D46E - ------------------------- - ---- Acknowledgments --- - ------------------------- Silicon Graphics wishes to thank the Internet community at large for their assistance in this matter. - ------------------------------------------------------------ - ---- Silicon Graphics Inc.
