Severity: HIGH
Attention: Java users, System Administrators, Desktop Support Personnel

Summary: Internet Security resources are reporting the existence of 11 security vulnerabilities in a popular range of Sun Java products.  The most likely method of exploit for these vulnerabilities is the visitation of a website that is hosting maliciously-crafted Java elements.  Successful exploitation of a vulnerable system could result in application crash or complete system takeover.  The vendor has made available upgrade software (patches) that fix these vulnerabilities.

Recommended Actions: Java Users are encouraged to apply the update(s) as soon as possible.

NOTE:
Java technology is commonly used by web browsers to provide interactive content via small programs called applets or plugins.  Many web browsers have Java products installed on them unbeknownst to the user.  It can sometimes be difficult to determine if Java is present on a computer (and if so what version or version or versions are running).  You can check for the presence of Java on your computer (and current running version or versions) by using the links listed in the "Resources" section below.

Readers are encouraged to share this alert with family, friends, and associates.

ITS Actions: N/A
