Sun Java Updates for Multiple Vulnerabilities

Original release date: July 11, 2008
Last revised:
Source: US-CERT

Systems Affected

Sun Java Runtime Environment versions
* JDK and JRE 6 Update 6 and earlier
* JDK and JRE 5.0 Update 16 and earlier
* SDK and JRE 1.4.2_17 and earlier
* SDK and JRE 1.3.1_22 and earlier

Overview

Sun has released alerts to address multiple vulnerabilities affecting the
Sun Java Runtime Environment. The most severe of these vulnerabilities could
allow a remote attacker to execute arbitrary code.

I. Description

The Sun Java Runtime Environment (JRE) allows users to run Java applications
in a browser or as standalone programs. Sun has released updates to the Java
Runtime Environment software to address multiple vulnerabilities. Further
details about these vulnerabilities are available in the US-CERT
Vulnerability Notes Database.

Sun released the following alerts to address these issues:
* 238628 Security Vulnerabilities in the Java Runtime Environment related
to the processing of XML Data
* 238666 A Security Vulnerability with the processing of fonts in the Java
Runtime Environment may allow Elevation of Privileges
* 238687 Security Vulnerabilities in the Java Runtime Environment
Scripting Language Support
* 238905 Multiple Security Vulnerabilities in Java Web Start may allow
Privileges to be Elevated
* 238965 Security Vulnerability in Java Management Extensions (JMX)
* 238966 Security Vulnerability in JDK/JRE Secure Static Versioning
* 238967 Security Vulnerability in the Java Runtime Environment Virtual
Machine may allow an untrusted Application or Applet to Elevate
Privileges
* 238968 Security Vulnerabilities in the Java Runtime Environment may
allow Same Origin Policy to be Bypassed

II. Impact

The impacts of these vulnerabilities vary. The most severe of these
vulnerabilities allows a remote attacker to execute arbitrary code.

III. Solution

Apply an update from Sun

These issues are addressed in the following versions of the Sun Java Runtime
environment:
* JDK and JRE 6 Update 7
* JDK and JRE 5.0 Update 16
* SDK and JRE 1.4.2_18
* SDK and JRE 1.3.1_23

If you install the latest version of Java, older versions may remain
installed on your computer. If you do not need these older versions, you can
remove them by following Sun's instructions.

Disable Java

Disable Java in your web browser, as described in the Securing Your Web
Browser document. While this does not fix the underlying vulnerabilities, it
does block a common attack vector.
