security flaw

Firefox before 1.0.5, Thunderbird before 1.0.5, Mozilla before 1.7.9, Netscape 8.0.2, and K-Meleon 0.9 runs XBL scripts even when Javascript has been disabled, which makes it easier for remote attackers to bypass such protection.

security flaw

Certain privileged UI code in Mozilla Firefox and Thunderbird before 1.5.0.4 calls content-defined setters on an object prototype, which allows remote attackers to execute code at a higher privilege than intended.

security flaw

Firefox 1.0 allows remote attackers to modify Boolean configuration parameters for the about:config site by using a plugin such as Flash, and the -moz-opacity filter, to display the about:config site then cause the user to double-click at a certain screen position, aka "Fireflashing."

security flaw

Firefox before 1.0 and Mozilla before 1.7.5 allows inactive (background) tabs to launch dialog boxes, which can allow remote attackers to spoof the dialog boxes from web sites in other windows and facilitate phishing attacks, aka the "Dialog Box Spoofing Vulnerability."

Mozilla Firefox and Thunderbird before 1.5.0.4 associates XUL attributes with the wrong URL under certain unspecified circumstances, which might allow remote attackers to bypass restrictions by causing a persisted string to be associated with the wrong URL.

security flaw

The browser user interface in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 does not properly distinguish between user-generated events and untrusted synthetic events, which makes it easier for remote attackers to perform dangerous actions that normally could only be performed manually by the user.

security flaw

Mozilla before 1.7, Firefox before 0.9, and Thunderbird before 0.7, allow remote web sites to hijack the user interface via the "chrome" flag and XML User Interface Language (XUL) files.

Unspecified versions of Mozilla Firefox allow remote attackers to cause a denial of service (crash) via a web page that contains a large number of nested marquee tags. NOTE: a followup post indicated that the initial report could not be verified.

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.

security flaw

Mozilla 1.7.8, Firefox 1.0.4, Camino 0.8.4, Netscape 8.0.2, and K-Meleon 0.9, and possibly other products that use the Gecko engine, allow remote attackers to cause a denial of service (application crash) via JavaScript that repeatedly calls an empty function.

IE Tab 1.0.9 plugin for Mozilla Firefox 1.5.0.3 allows remote user-assisted attackers to cause a denial of service (application crash), possibly due to a null dereference, via certain Javascript, as demonstrated using a url parameter to the content/reloaded.html page in a chrome:// URI. Some third-party researchers claim that they are unable to reproduce this vulnerability.

security flaw

Firefox 1.0 does not invoke the Javascript Security Manager when a user drags a javascript: or data: URL to a tab, which allows remote attackers to bypass the security model, aka "firetabbing."

Mozilla Firefox 1.5.0.3 allows remote attackers to cause a denial of service via a web page with a large number of IMG elements in which the SRC attribute is a mailto URI. NOTE: another researcher found that the web page caused a temporary browser slowdown instead of a crash.

security flaw

A regression error in Firefox 1.0.3 and Mozilla 1.7.7 allows remote attackers to inject arbitrary Javascript from one page into the frameset of another site, aka the frame injection spoofing vulnerability, a re-introduction of a vulnerability that was originally identified and addressed by CVE-2004-0718.

Argument injection vulnerability in Mozilla Firefox 1.0.6 allows user-assisted remote attackers to modify command line arguments to an invoked mail client via " (double quote) characters in a mailto: scheme handler, as demonstrated by launching Microsoft Outlook with an arbitrary filename as an attachment. NOTE: it is not clear whether this issue is implementation-specific or a problem in the Microsoft API.

The file download dialog in Mozilla Firefox 0.10.1 and 1.0 for Windows uses the Content-Type HTTP header to determine the file type, but saves the original file extension when "Save to Disk" is selected, which allows remote attackers to hide the real file types of downloaded files.

Mozilla Firefox 1.5.0.2, when designMode is enabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code via certain Javascript that is not properly handled by the contentWindow.focus method in an iframe, which causes a reference to a deleted controller context object. NOTE: this was originally claimed to be a buffer overflow in (1) js320.dll and (2) xpcom_core.dll, but the vendor disputes this claim.

Firefox 1.0 does not prevent the user from dragging an executable file to the desktop when it has an image/gif content type but has a dangerous extension such as .bat or .exe, which allows remote attackers to bypass the intended restriction and execute arbitrary commands via malformed GIF files that can still be parsed by the Windows batch file parser, aka "firedragging."

Mozilla Firefox 1.5.0.2 and possibly other versions before 1.5.0.4, Netscape 8.1, 8.0.4, and 7.2, and K-Meleon 0.9.13 allows user-assisted remote attackers to open local files via a web page with an IMG element containing a SRC attribute with a non-image file:// URL, then tricking the user into selecting View Image for the broken image, as demonstrated using a .wma file to launch Windows Media Player, or by referencing an "alternate web page."

Firefox and Mozilla allow remote attackers to cause a denial of service (application crash from memory consumption), as demonstrated using Javascript code that continuously creates nested arrays and then sorts the newly created arrays.
