Sun(sm) Alert Notification
* Sun Alert ID: 102934
* Synopsis: Security Vulnerabilities in the Java Runtime Environment
Image Parsing Code May Allow a Untrusted Applet to Elevate
Privileges
* Category: Security
* Product: Java 2 Platform, Standard Edition
* BugIDs: 6483556, 6483560
* Avoidance: Patch, Upgrade
* State: Resolved
* Date Released: 31-May-2007, 29-Jun-2007
* Date Closed: 29-Jun-2007

1. 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.

2. 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.
