Unspecified vulnerability in the Virtual Machine in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 6 Update 12 and earlier allows remote attackers to access files and execute arbitrary code via unknown vectors related to "code generation."

The Java Plug-in in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 5.0 Update 17 and earlier; 6 Update 12 and earlier; and 1.4.219 and earlier does not prevent Javascript that is loaded from the localhost from connecting to other ports on the system, which allows user-assisted attackers to bypass intended access restrictions via LiveConnect, aka CR 6724331. NOTE: this vulnerability can be leveraged with separate cross-site scripting (XSS) vulnerabilities for remote attack vectors.

The Java Plug-in in Java SE Development Kit (JDK) and Java Runtime Environment (JRE) 6 Update 12 and earlier, and 5.0 Update 17 and earlier, allows remote attackers to trick a user into trusting a signed applet via unknown vectors that misrepresent the security warning dialog, related to a "Swing JLabel HTML parsing vulnerability," aka CR 6782871.
