Two Security Vulnerabilities in the Java Runtime Environment Virtual Machine
1. Impact
Two security vulnerabilities in the Java Runtime Environment Virtual
Machine may
independently 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.
Sun acknowledges with thanks, Fujitsu for bringing the first issue to
our attention.
2. Contributing Factors
The first issue 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
- SDK and JRE 1.4.2_16 and earlier
Note: SDK and JRE 1.3.x is not
affected by this issue.
The second issue can occur in the following releases (for Windows,
Solaris, and Linux):
- JDK and JRE 5.0 Update 13 and earlier
- SDK and JRE 1.4.2_16 and earlier
Note: JDK and JRE 6, and SDK
and JRE 1.3.x are not affected by this issue.
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.
5. Resolution
The first issue is addressed in the following releases (for Windows,
Solaris, and Linux):
- JDK and JRE 6 Update 5 or later
- JDK and JRE 5.0 Update 15 or later
- SDK and JRE 1.4.2_17 or later
The second issue is addressed in the following releases (for Windows,
Solaris, and Linux):
