Mozilla : Security Vulnerabilities, CVEs, Published In July 2005 (Code Execution)

Firefox before 1.0.5 and Mozilla before 1.7.9 does not properly clone base objects, which allows remote attackers to execute arbitrary code by navigating the prototype chain to reach a privileged object.

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, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 allows remote attackers to cause a denial of service (access violation and crash), and possibly execute arbitrary code, by calling InstallVersion.compareTo with an object instead of a string.

Firefox 1.0.3 and 1.0.4, and Netscape 8.0.2, allows remote attackers to execute arbitrary code by tricking the user into using the "Set As Wallpaper" (in Firefox) or "Set as Background" (in Netscape) context menu on an image URL that is really a javascript: URL with an eval statement, aka "Firewalling."
