Java Web Start in Sun JDK and JRE 6 Update 2 and earlier does not properly enforce access restrictions for untrusted applications, which allows user-assisted remote attackers to read and modify local files via an untrusted application, aka "two vulnerabilities."
Unspecified vulnerability in the Java Runtime Environment (JRE) Swing library in JDK and JRE 5.0 Update 7 and earlier allows attackers to obtain certain information via unknown attack vectors, related to an untrusted applet accessing data in other applets.
Java Runtime Environment (JRE) Bytecode Verifier allows remote attackers to escape the Java sandbox and execute commands via an applet containing an illegal cast operation, as seen in (1) Microsoft VM build 3802 and earlier as used in Internet Explorer 4.x and 5.x, (2) Netscape 6.2.1 and earlier, and possibly other implementations that use vulnerable versions of SDK or JDK, aka a variant of the "Virtual Machine Verifier" vulnerability.
Vulnerability in Java Runtime Environment (JRE) allows remote malicious web sites to hijack or sniff a web client's sessions, when an HTTP proxy is being used, via a Java applet that redirects the session to another server, as seen in (1) Netscape 6.0 through 6.1 and 4.79 and earlier, (2) Microsoft VM build 3802 and earlier as used in Internet Explorer 4.x and 5.x, and possibly other implementations that use vulnerable versions of SDK or JDK.
Java Runtime Environment in Java Development Kit (JDK) 1.2.2_05 and earlier can allow an untrusted Java class to call into a disallowed class, which could allow an attacker to escape the Java sandbox and conduct unauthorized activities.
