Security Vulnerabilities in the Java Runtime Environment Image Parsing Code May Allow a Untrusted Applet to Elevate Privileges



Category
Security

Release Phase
Resolved

Product
Java 2 Platform, Standard Edition

Bug Id
6483556, 6483560

Date of Workaround Release
31-MAY-2007

Date of Resolved Release
29-JUN-2007

Impact

A buffer overflow vulnerability in the image parsing code in the Java Runtime Environment may allow an untrusted applet or application 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.

A second vulnerability may allow an untrusted applet or application to cause the Java Virtual Machine to hang.

Sun acknowledges, with thanks, Chris Evans of the Google Security Team, for bringing these issues to our attention.

These issues are also referenced in the following documents:

CVE-2007-2788 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2788

CVE-2007-2789 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2789


Contributing Factors

These issues can occur in the following releases (for Windows, Solaris, and Linux):

First vulnerability:

  • JDK and JRE 6
  • JDK and JRE 5.0 Update 10 and earlier
  • SDK and JRE 1.4.2_14 and earlier
  • SDK and JRE 1.3.1_20 and earlier

Second vulnerability:

  • JDK and JRE 6
  • JDK and JRE 5.0 Update 10 and earlier
  • SDK and JRE 1.4.2_14 and earlier
  • SDK and JRE 1.3.1_19 and earlier

To determine the default version of the JRE on a system for Solaris and Linux, the following command can be run:

    % java -version

Note: The above command only determines the default version. Other versions may also be installed on the system.

To determine the default version of the JRE on a system for Windows:

  1. Click "Start"
  2. Select "Run"
  3. Type "cmd" (starts a command-line)
  4. At the prompt, type "java -version"

Note: The above command only determines the default version. Other versions may also be installed on the system.
