Vulnerabilties in the Java Runtime Environment Image Parsing Library
1. Impact
A vulnerability in the Java Runtime Environment image parsing library
may allow an untrusted application or applet that is downloaded from a
website to elevate its privileges. For example, the application or
applet may grant itself permissions to read and write local files or
execute local applications that are accessible to the user running the
untrusted application or applet.
Two vulnerabilities in the color management library may allow an
untrusted applet or application or applet to cause the Java Runtime
Environment to crash, which
is a type of Denial of Service (DoS).
Sun acknowledges with thanks, Chris Evans of the Google Security Team
for bringing the first two issues
to our attention.
2. Contributing Factors
These issues can occur in the following releases (for Windows, Solaris,
and Linux):
- JDK and JRE 6 Update 4 and earlier
- JDK and JRE 5.0 Update 14 and earlier
Note: SDK and JRE 1.4.x and
1.3.x are not affected
To determine the default version of the JRE that Internet Explorer uses:
- Click "Tools" in the Menu Bar at the top of the browser
- Select "Sun Java Console"
The first two lines in the console displays the version of Java Plug-in
and JRE that Internet Explorer uses.
To determine the default version of the JRE that Mozilla or Firefox
browsers use, visit the URL "about:plugins". The browser will display a
page called "Installed plug-ins" which lists the version of the Java
Plug-in such as the following:
Java(TM) Plug-in 1.5.0_11-b03
The above indicates the version of the JRE the browser uses
is 1.5.0_11.
3. Symptoms
There are no predictable symptoms that would indicate that the above
issues are being exploited.
4. Workaround
There is no workaround for these issues. Please see the Resolution
section below.
