Mozilla Firefox — свободный браузер на движке Gecko

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.

Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 does not properly verify the associated types of DOM node names within the context of their namespaces, which allows remote attackers to modify certain tag properties, possibly leading to execution of arbitrary script or code, as demonstrated using an XHTML document with IMG tags with custom properties ("XHTML node spoofing").

Firefox before 1.0.5 allows remote attackers to steal information and possibly execute arbitrary code by using standalone applications such as Flash and QuickTime to open a javascript: URL, which is run in the context of the previous page, and may lead to code execution if the standalone application loads a privileged chrome: URL.

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.

Firefox before 1.0.5 and Mozilla before 1.7.9 allows a child frame to call top.focus and other methods in a parent frame, even when the parent is in a different domain, which violates the same origin policy and allows remote attackers to steal sensitive information such as cookies and passwords from web sites whose child frames do not verify that they are in the same domain as their parents.

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.

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.
