Mozilla Firefox 1.5.0.4, 2.0.x before 2.0.0.8, Mozilla Suite 1.7.13, Mozilla SeaMonkey 1.0.2 and other versions before 1.1.5, and Netscape 8.1 and earlier allow user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename in a text box and using the OnKeyDown, OnKeyPress, and OnKeyUp Javascript keystroke events to change the focus and cause those characters to be inserted into a file upload input control, which can then upload the file when the user submits the form.

Mozilla Suite 1.7.13, Mozilla Firefox 1.5.0.3 and possibly other versions before before 1.8.0, and Netscape 7.2 and 8.1, and possibly other versions and products, allows remote user-assisted attackers to obtain information such as the installation path by causing exceptions to be thrown and checking the message contents.

Unspecified vulnerability in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to cause a denial of service (crash) by changing the (1) -moz-grid and (2) -moz-grid-group display styles.

Mozilla Firefox 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to read arbitrary files by (1) inserting the target filename into a text box, then turning that box into a file upload control, or (2) changing the type of the input control that is associated with an event handler.

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 does not properly protect the compilation scope of privileged built-in XBL bindings, which allows remote attackers to execute arbitrary code via the (1) valueOf.call or (2) valueOf.apply methods of an XBL binding, or (3) "by inserting an XBL method into the DOM's document.body prototype chain."

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 returns the Object class prototype instead of the global window object when (1) .valueOf.call or (2) .valueOf.apply are called without any arguments, which allows remote attackers to conduct cross-site scripting (XSS) attacks.

Mozilla Firefox 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to inject arbitrary Javascript into other sites by (1) "using a modal alert to suspend an event handler while a new page is being loaded", (2) using eval(), and using certain variants involving (3) "new Script;" and (4) using window.proto to extend eval, aka "cross-site JavaScript injection".

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to execute arbitrary code by using the Object.watch method to access the "clone parent" internal function.

The JavaScript engine in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 does not properly handle temporary variables that are not garbage collected, which might allow remote attackers to trigger operations on freed memory and cause memory corruption.

Mozilla Firefox 1.5, Netscape 8.0.4 and 7.2, and K-Meleon before 0.9.12 allows remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. NOTE: despite initial reports, the Mozilla vendor does not believe that this issue can be used to trigger a crash or buffer overflow in Firefox. Also, it has been independently reported that Netscape 8.1 does not have this issue.

Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to spoof DOM objects via an XBL control that implements an internal XPCOM interface.

Firefox before 1.0.7 and Mozilla before Suite 1.7.12 allows remote attackers to execute Javascript with chrome privileges via an about: page such as about:mozilla.

Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to modify HTTP headers of XML HTTP requests via XMLHttpRequest, and possibly use the client to exploit vulnerabilities in servers or proxies, including HTTP request smuggling and HTTP request splitting.

Firefox before 1.0.7 and Mozilla Suite before 1.7.12 allows remote attackers to spawn windows without user interface components such as the address and status bar, which could be used to conduct spoofing or phishing attacks.
