Oracle Java SE Executive Summary

This Security Alert contains 1 new security fix for Oracle Java SE. This vulnerability is remotely exploitable without authentication, i.e., may be exploited over a network without the need for a username and password. The English text form of this Risk Matrix can be found here.

The CVSS scores below assume that a user running a Java applet or Java Web Start application has administrator privileges (typical on Windows). When the user does not run with administrator privileges (typical on Solaris and Linux), the corresponding CVSS impact scores for Confidentiality, Integrity, and Availability are "Partial" instead of "Complete", lowering the CVSS Base Score. For example, a Base Score of 10.0 becomes 7.5.
