Title : Netscape Browsers Vulnerabilities. Number : 20030102-01-I Date : January 7, 2003 Reference: CERT CA-2000-8 Reference: CERT CA-2000-5 Reference: CERT CA-2000-15 Reference: BUGTRAQ ID# 1726 Reference: SGI BUG 818218 820013 Fixed in : IRIX 6.5.13 and higher Fixed in : Netscape 4.79 and higher ______________________________________________________________________________ - ----------------------- - --- Issue Specifics --- - ----------------------- It's been reported that Netscape Navigator and Communicator versions prior to 4.77 have numerous security vulnerabilities that can be exploited by a remote user. These Netscape products are not produced by SGI, but we supply them with the IRIX operating system. Please see the following URLs for additional details. http://www.securityfocus.com/bid/1726 http://www.securityfocus.com/archive/1/175060 http://www.cert.org/advisories/CA-2000-08.html http://www.cert.org/advisories/CA-2000-05.html http://www.cert.org/advisories/CA-2000-15.html http://wp.netscape.com/security/notes/index.html 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 in the versions of Netscape supplied with IRIX 6.5.13 and later versions. - -------------- - --- Impact --- - -------------- The netscape binary is installed by default on IRIX 6.5 systems as part of netscape.sw.client from the IRIX Applications CD. 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 6.5.16f 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 netscape is installed, execute the following command: $ versions netscape.sw.client I = Installed, R = Removed Name Date Description I netscape 11/19/2002 Netscape Communicator Client, 4.8 I netscape.sw 11/19/2002 Netscape Communicator Software Environment, 4.8 I netscape.sw.client 11/19/2002 Netscape Communicator Client, 4.8 You can also use the 'netscape -v' command for more version information and you should see: Netscape 4.8/U.S., 29-Oct-02; (c) 1995-2000 Netscape Communications Corp. The above listings show netscape version 4.8. If the version shown when you run the command is 4.76 or earlier, then the system is vulnerable. - ---------------------------- - --- Temporary Workaround --- - ---------------------------- There is no effective workaround available for these problems. SGI recommends either upgrading to IRIX 6.5.13, or Netscape 4.79 is available for Free download from http://www.sgi.com/products/evaluation and the Netscape 4.8 release will be available by February. - ---------------- - --- Solution --- - ---------------- SGI has not provided patches for these vulnerabilities. Our recommendation is to upgrade to IRIX 6.5.13 or later. OS Version Vulnerable?
