Java Web Start in Sun JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, and SDK and JRE 1.4.2_15 and earlier does not properly enforce access restrictions for untrusted applications, which allows user-assisted remote attackers to obtain sensitive information (the Java Web Start cache location) via an untrusted application, aka "three vulnerabilities."

Java Web Start in Sun JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier does not properly enforce access restrictions for untrusted (1) applications and (2) applets, which allows user-assisted remote attackers to copy or rename arbitrary files when local users perform drag-and-drop operations from the untrusted application or applet window onto certain types of desktop applications.

Visual truncation vulnerability in the Java Runtime Environment in Sun JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier allows remote attackers to circumvent display of the untrusted-code warning banner by creating a window larger than the workstation screen.

Sun Java Runtime Environment (JRE) in JDK and JRE 6 Update 2 and earlier, JDK and JRE 5.0 Update 12 and earlier, SDK and JRE 1.4.2_15 and earlier, and SDK and JRE 1.3.1_20 and earlier, when applet caching is enabled, allows remote attackers to violate the security model for an applet's outbound connections via a DNS rebinding attack.

Sun Java JRE 1.1.x through 1.4.x writes temporary files with long filenames that become predictable on a file system that uses 8.3 style short names, which allows remote attackers to write arbitrary files to known locations and facilitates the exploitation of vulnerabilities in applications that rely on unpredictable file names.
