From agent99@sgi.com Wed Jan 22 15:29:21 2003 From: SGI Security Coordinator To: agent99@sgi.com Newsgroups: comp.sys.sgi.announce, comp.security.unix, comp.sys.sgi.admin, comp.security.announce Date: Tue, 21 Jan 2003 12:42:38 -0800 Subject: IRIX ToolTalk RPC Server Format String Vulnerability update -----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SGI Security Advisory Title : IRIX ToolTalk RPC Server Format String Vulnerability update Number : 20021102-02-P Date : January 21, 2003 Reference: CERT CA-1999-11 Reference: CAN-2002-0677 Reference: CAN-2002-0678 Reference: SGI Security Advisory 20021102-01-P Reference: SGI BUGS 872674 833473 860031 861480 872674 Fixed in : IRIX 6.5.18 or patch 4869 ______________________________________________________________________________ - ----------------------- - --- Issue Specifics --- - ----------------------- This bulletin is an update to SGI Security Bulletin 20021102-01-P, see ftp://patches.sgi.com/support/free/security/advisories/20021102-01-P. The patch referenced in 20021102-01-P did not apply cleanly in some instances. A new patch has been created that will apply cleanly on current IRIX systems. In addition to the items outlined in the above bulletin, this bulletin and the fixes noted herein fix vulnerability #2 in CERT CA-1999-11. See http://www.cert.org/advisories/CA-1999-11.html for additional details. 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 a patch and in IRIX 6.5.18. - -------------- - --- Impact --- - -------------- The rpc.ttdbserverd binary is not installed by default on IRIX 6.5 systems. It is part of the optional IRIX ToolTalk package (tooltalk_eoe.sw.runtime). 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 6.5.16f 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 rpc.ttdbserverd is installed, execute the following command: # versions long | grep rpc.ttdbserverd f 1868 699 tooltalk_eoe.sw.runtime usr/ToolTalk/etc/rpc.ttdbserverd l 0 0 tooltalk_eoe.man.manpages usr/ToolTalk/man1m/rpc.ttdbserverd.z l 0 0 tooltalk_eoe.sw.links usr/etc/rpc.ttdbserverd If the output of the command is similar to the above, then rpc.ttdbserverd is installed and the system may be vulnerable. - ---------------------------- - --- Temporary Workaround --- - ---------------------------- There is no effective workaround available for these problems if you need to use tooltalk. SGI recommends either upgrading to IRIX 6.5.18 or later, or installing the appropriate patch from the listing below. - ---------------- - --- Solution --- - ---------------- SGI has provided a patch for these vulnerabilities. Our recommendation is to upgrade to IRIX 6.5.18 or later, or install the appropriate patch. OS Version Vulnerable?
