Description:
Sun has acknowledged a security issue in Sun Java Runtime Environment (JRE), which can be exploited by malicious people to bypass certain security restrictions.
The security issue is caused due to the JRE processing external XML entity references even though the "external general entities" property is set to FALSE. This can be exploited to e.g. access certain URLs or cause a DoS (Denial of Service) via malicious XML documents.
Successful exploitation requires that malicious XML data is processed within a trusted applet or Java Web Start application.
The security issue is reported in Sun JDK and JRE 6 Update 3 and earlier. Sun JDK and JRE 5.0, and SDK and JRE 1.4.x and 1.3.x are reportedly not affected.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, using the Network Software Inspector.
Solution:
Update to JDK or JRE 6 Update 4 or later.
http://java.sun.com/javase/downloads/index.jsp
JDK 6 Update 4 for Solaris is also available in the following patches:
Java SE 6 update 4 (as delivered in patch 125136-05 or later)
