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, 11, and 10 allows user-assisted remote attackers to cause a trusted applet to run in an older JRE version, which can be used to exploit vulnerabilities in that older version, aka CR 6706490.

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.

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."

Unspecified vulnerability in 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; 1.4.219 and earlier; and 1.3.124 and earlier allows remote attackers to access files and execute arbitrary code via unknown vectors related to "deserializing applets," aka CR 6646860.

Sun Java 1.3.1, 1.4.1, and 1.4.2 allows local users to cause a denial of service (JVM crash), possibly by calling the ClassDepth function with a null parameter, which causes a crash instead of generating a null pointer exception.

The byte code verifier component of the Java Virtual Machine (JVM) allows remote execution through malicious web pages.

The Java Applet Security Manager implementation in Netscape Navigator 2.0 and Java Developer's Kit 1.0 allows an applet to connect to arbitrary hosts.

Unspecified vulnerability in the New Java Plug-in component in Oracle Java SE and Java for Business JDK and JRE 6 Update 18 and 19 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors.

Java 1.4.2 before 1.4.2 Release 2 on Apple Mac OS X does not prevent multiple programs from opening the same port as a Java ServerSocket, which allows local users to operate a Java program that intercepts network data intended for the ServerSocket of a different Java program.

Unspecified vulnerability in Java 1.4.2 before 1.4.2 Release 2 on Apple Mac OS X allows local users to gain privileges via unspecified attack vectors relating to "the utility used to update Java shared archives."

Race condition in Java 1.4.2 before 1.4.2 Release 2 on Apple Mac OS X allows local users to corrupt files or create arbitrary files via unspecified attack vectors related to a temporary directory, possibly due to a symlink attack.

Unspecified vulnerability in Java 1.3.1 before 1.3.116 on Apple Mac OS X allows an untrusted applet to gain privileges, related to "Mac OS X specific extensions."
