Vulnerability Note VU#939609

Sun Java JRE vulnerable to arbitrary code execution via an unspecified error

Overview

A vulnerability in the Sun Java Runtime Environment may allow an attacker to execute arbitrary code on a vulnerable system.

I. Description

The Sun Java Runtime Environment (JRE) allows users to run Java applications in a browser or as standalone programs. Sun has made the JRE available for multiple operating systems.

Per Sunsolve Document ID 102729:

    Two buffer overflow vulnerabilities in the Java Runtime Environment may independently allow an untrusted applet to elevate its privileges. For example, an 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.

II. Impact

A remote unauthenticated attacker may be able to execute arbitrary code.

III. Solution

Upgrade

Sun has released an upgrade to address this issue. See Sunsolve Document ID 102729 for more details. To adjust the JRE update settings, see the update section of the Java deployment guide.

Disable Java

Disabling the Java browser plugin may prevent a malicious webpage from exploiting this vulnerability. See the Securing Your Web Browser for instructions on how to disable Java in your browser.
