SGI Security Advisory
Title: Netscape JAVA JRE vulnerability
Number: 20020807-01-I
Date: August 29, 2002
Reference: CAN-2002-0058
Reference: SUN Security Advisory #0216
_____________________________________________________________________________
- - -----------------------
- - --- Issue Specifics ---
- - -----------------------
It has been reported that the Netscape Communicator versions that SGI has
shipped with IRIX have security vulnerabilities in the JAVA JRE code.
See http://home.netscape.com/security/
http://sunsolve.Sun.COM/pub-cgi/retrieve.pl?doctype=coll&doc=secbull/216
...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 in future releases of IRIX.
- - --------------
- - --- Impact ---
- - --------------
The Netscape Communicator package is not installed by default on IRIX 6.5
systems, it is supplied on 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 Communicator is installed, execute the following command:
$ versions -b netscape
I = Installed, R = Removed
Name Date Description
I netscape 09/19/2001 Netscape Communicator Client, 4.79
If the netscape package is installed, the system is vulnerable.
This vulnerability was assigned the following CVE:
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2002-0058
- - ----------------------------
- - --- Temporary Workaround ---
- - ----------------------------
SGI realizes that there are times when upgrading the operating system is
inconvenient or not possible, and in those cases we recommend that you visit
the following URL and install the upgraded Java Runtime Environment (JRE)
available there:
http://www.sgi.com/products/evaluation/6.x_java_plugin_1.1.1/
The upgraded Java Runtime Environment (JRE), 1.3.1_02, is available from:
http://www.sgi.com/products/evaluation/6.5_java2_1.3.1_02/
To get Netscape to use the upgraded JRE, you should have the Netscape
Java plugin installed, available from:
http://www.sgi.com/products/evaluation/6.x_java_plugin_1.1.1/
Another workaround would be to disable Java support at
Preferences->Advanced, but obviously this will remove functionality.
- - ----------------
- - --- Solution ---
- - ----------------
With IRIX 6.5.18, JRE 1.3.1_02 will be on the 6.5.18 Applications CD, so
browsers with the Java plugin can use it by default. Our recommendation is
to upgrade to IRIX 6.5.18 when it becomes available.
