Java Plugin 1.4 for JRE 1.3 executes signed applets even if the certificate is expired, which could allow remote attackers to conduct unauthorized activities via an applet that has been signed by an expired certificate.

Trend Micro InterScan AppletTrap 2.0 does not properly filter URLs when they are modified in certain ways such as (1) using a double slash (//) instead of a single slash, (2) URL-encoded characters, (3) requesting the IP address instead of the domain name, or (4) using a leading 0 in an octet of an IP address.

Windows 98 and Windows 2000 Java clients allow remote attackers to cause a denial of service via a Java applet that opens a large number of UDP sockets, which prevents the host from establishing any additional UDP connections, and possibly causes a crash.

Windows Media Player 7 allows remote attackers to execute malicious Java applets in Internet Explorer clients by enclosing the applet in a skin file named skin.wmz, then referencing that skin in the codebase parameter to an applet tag, aka the Windows Media Player Skins File Download" vulnerability.

Two Sun security certificates have been compromised, which could allow attackers to insert malicious code such as applets and make it appear that it is signed by Sun.

Mac OS Runtime for Java (MRJ) 2.2.3 allows remote attackers to use malicious applets to read files outside of the CODEBASE context via the ARCHIVE applet parameter.

Microsoft Virtual Machine (VM) in Internet Explorer 4.x and 5.x allows an unsigned applet to create and use ActiveX controls, which allows a remote attacker to bypass Internet Explorer's security settings and execute arbitrary commands via a malicious web page or email, aka the "Microsoft VM ActiveX Component" vulnerability.

Netscape Communicator and Navigator 4.04 through 4.74 allows remote attackers to read arbitrary files by using a Java applet to open a connection to a URL using the "file", "http", "https", and "ftp" protocols, as demonstrated by Brown Orifice.

Netscape Communicator does not properly prevent a ServerSocket object from being created by untrusted entities, which allows remote attackers to create a server on the victim's system via a malicious applet, as demonstrated by Brown Orifice.

AppleShare IP 6.1 and later allows a remote attacker to read potentially sensitive information via an invalid range request to the web server.

Internet Explorer 5.01 allows remote attackers to bypass the cross frame security policy via a malicious applet that interacts with the Java JSObject to modify the DOM properties to set the IFRAME to an arbitrary Javascript URL.

Panda Security 3.0 allows users to uninstall the Panda software via its Add/Remove Programs applet.

Netscape Enterprise Server with Web Publishing enabled allows remote attackers to list arbitrary directories via a GET request for the /publisher directory, which provides a Java applet that allows the attacker to browse the directories.

The Microsoft virtual machine (VM) in Internet Explorer 4.x and 5.x allows a remote attacker to read files via a malicious Java applet that escapes the Java sandbox, aka the "VM File Reading" vulnerability.

Internet Explorer allows remote attackers to read files by redirecting data to a Javascript applet.

The Microsoft Java Virtual Machine allows a malicious Java applet to execute arbitrary commands outside of the sandbox environment.

Microsoft Virtual Machine (VM) allows remote attackers to escape the Java sandbox and execute commands via an applet containing an illegal cast operation, aka the "Virtual Machine Verifier" vulnerability.

A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes.

Control Panel "Password Security" option for Apple Powerbooks allows attackers with physical access to the machine to bypass the security by booting it with an emergency startup disk and using a disk editor to modify the on/off toggle or password in the aaaaaaaAPWD file, which is normally inaccessible.

Buffer overflow in Apple AppleShare Mail Server 5.0.3 on MacOS 8.1 and earlier allows a remote attacker to cause a denial of service (crash) via a long HELO command.
