Some vulnerabilities have been reported in Sun Java JRE (Java Runtime Environment), which can be exploited by malicious people to compromise a users system.
1) An unspecified error may be exploited by a malicious, untrusted applet to read and write local files or execute local applications.
The vulnerability has been reported in JDK/JRE 5.0 Update 3 and prior on Windows, Solaris and Linux platforms. SDK/JRE 1.4.2_xx and prior, and 1.3.1_xx releases are not affected.
2) Three unspecified vulnerabilities with the use of 'reflection' APIs error may be exploited by a malicious, untrusted applet to read and write local files or execute local applications.
The following releases are affected by one or more of the three vulnerabilities on Windows, Solaris and Linux platforms:
* SDK and JRE 1.3.1_15 and prior.
* SDK and JRE 1.4.2_08 and prior.
* JDK and JRE 5.0 Update 3 and prior.
3) An unspecified error in the JMX (Java Management Extensions) implementation included with the JRE may be exploited by a malicious, untrusted applet to read and write local files or execute local applications.
The vulnerability has been reported in JDK/JRE 5.0 Update 3 and prior on Windows, Solaris and Linux platforms. SDK/JRE 1.4.2_xx and prior, and 1.3.1_xx releases are not affected.
Solution:
Update to the fixed versions:
JDK and JRE 5.0:
Update to JDK and JRE 5.0 Update 4 or later.
http://java.sun.com/j2se/1.5.0/download.jsp
SDK and JRE 1.4.x:
Update to SDK and JRE 1.4.2_09 or later.
http://java.sun.com/j2se/1.4.2/download.html
SDK and JRE 1.3.x:
