Mozilla Firefox 2.0 before 2.0.0.8 allows remote attackers to obtain sensitive system information by using the addMicrosummaryGenerator sidebar method to access file: URIs.

Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5 can hide the window's titlebar when displaying XUL markup language documents, which makes it easier for remote attackers to conduct phishing and spoofing attacks by setting the hidechrome attribute.

Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5, when running on Linux systems with gnome-vfs support, might allow remote attackers to read arbitrary files on SSH/sftp servers that accept key authentication by creating a web page on the target server, in which the web page contains URIs with (1) smb: or (2) sftp: schemes that access other files from the server.

Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5 allow remote attackers to execute arbitrary Javascript with user privileges by using the Script object to modify XPCNativeWrappers in a way that causes the script to be executed when a chrome action is performed.

Multiple vulnerabilities in Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allow remote attackers to cause a denial of service (crash) via crafted HTML that triggers memory corruption or assert errors.

Multiple vulnerabilities in the Javascript engine in Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allow remote attackers to cause a denial of service (crash) via crafted HTML that triggers memory corruption.

Argument injection vulnerability in Apple QuickTime 7.1.5 and earlier, when running on systems with Mozilla Firefox before 2.0.0.7 installed, allows remote attackers to execute arbitrary commands via a QuickTime Media Link (QTL) file with an embed XML element and a qtnext parameter containing the Firefox "-chrome" argument. NOTE: this is a related issue to CVE-2006-4965 and the result of an incomplete fix for CVE-2007-3670.

Mozilla Firefox before Firefox 2.0.0.13, and SeaMonkey before 1.1.9, can automatically install TLS client certificates with minimal user interaction, and automatically sends these certificates when requested, which makes it easier for remote web sites to track user activities across domains by requesting the TLS client certificates from other domains.

Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allows remote attackers to execute arbitrary commands via a (1) mailto, (2) nntp, (3) news, or (4) snews URI with invalid "%" encoding, related to improper file type handling on Windows XP with Internet Explorer 7 installed, a variant of CVE-2007-3845.

Mozilla Firefox 2.0.0.6 and earlier allows remote attackers to spoof the contents of the status bar via a link to a data: URI containing an encoded URL. NOTE: the severity of this issue has been disputed by a reliable third party, since the intended functionality of the status bar allows it to be modified.

Argument injection vulnerability in Mozilla Firefox before 2.0.0.5, when running on systems with Thunderbird 1.5 installed and certain URIs registered, allows remote attackers to conduct cross-browser scripting attacks and execute arbitrary commands via shell metacharacters in a mailto URI, which are inserted into the command line that is created when invoking Thunderbird.exe, a similar issue to CVE-2007-3670.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 2.0.0.5 and Thunderbird before 2.0.0.5 allow remote attackers to cause a denial of service (crash) via unspecified vectors that trigger memory corruption.

Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox before 2.0.0.5 and Thunderbird before 2.0.0.5 allow remote attackers to cause a denial of service (crash) via unspecified vectors that trigger memory corruption.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 2.0.0.5 allows remote attackers to inject arbitrary web script "into another site's context" via a "timing issue" involving the (1) addEventListener or (2) setTimeout function, probably by setting events that activate after the context has changed.

Mozilla Firefox before 2.0.0.5 allows remote attackers to execute arbitrary code with chrome privileges by calling an event handler from an unspecified "element outside of a document."

Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.5 allow remote attackers to execute arbitrary code via a crafted XPCNativeWrapper.

Mozilla Firefox 2.0.0.4 allows remote attackers to cause a denial of service by opening multiple tabs in a popup window. NOTE: this issue has been disputed by third party researchers, stating that "this does not crash on me, and I can't see a likely mechanism of action that would lead to a DoS condition.

The focus handling for the onkeydown event in Mozilla Firefox 1.5.0.12, 2.0.0.4 and other versions before 2.0.0.8, and SeaMonkey before 1.1.5 allows remote attackers to change field focus and copy keystrokes via the "for" attribute in a label, which bypasses the focus prevention, as demonstrated by changing focus from a textarea to a file upload field.

Mozilla Firefox before 2.0.0.5, when run on Windows, allows remote attackers to bypass file type checks and possibly execute programs via a (1) file:/// or (2) resource: URI with a dangerous extension, followed by a NULL byte (%00) and a safer extension, which causes Firefox to treat the requested file differently than Windows would.

Mozilla Firefox before 2.0.0.5 does not prevent use of document.write to replace an IFRAME (1) during the load stage or (2) in the case of an about:blank frame, which allows remote attackers to display arbitrary HTML or execute certain JavaScript code, as demonstrated by code that intercepts keystroke values from window.event, aka the "promiscuous IFRAME access bug," a related issue to CVE-2006-4568.
