Security Vulnerabilities With Java Plug-in in JRE/SDK



Category
Security

Release Phase
Resolved

Bug Id
4883871, 5004017

Date of Resolved Release
18-JAN-2005

Impact

A vulnerability in the Java Plug-in may allow an untrusted applet to elevate privileges through JavaScript calling into Java code. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet.

A second vulnerability may allow an untrusted applet to inappropriately interfere with another applet in the same web page which may include causing it to incorrectly load non-code resources such as files and web pages.

Sun acknowledges, with thanks, Fujitsu, for bringing these issues to our attention.


Contributing Factors

The first issue can occur in the following releases:

  • SDK and JRE 1.4.2, 1.4.1_06 and earlier, all 1.4.0 releases, and 1.3.1_12 and earlier for Windows using the Internet Explorer browser

The second issue can occur in the following releases:

  • SDK and JRE 1.4.2_05 and earlier, all 1.4.1 and 1.4.0 releases, and 1.3.1_12 and earlier for Windows, Solaris and Linux

Note: JDK and JRE 5.0 are not affected by these vulnerabilities.

To determine the version of Java on a system, the following command can be run:

    % java -fullversion
java full version "1.4.1_06-b01"

Symptoms

There are no reliable symptoms that would indicate the described issues have been exploited.
