Firefox before 1.0.4 and Mozilla Suite before 1.7.8 do not properly limit privileges of Javascript eval and Script objects in the calling context, which allows remote attackers to conduct unauthorized activities via "non-DOM property overrides," a variant of CVE-2005-1160.

Firefox 1.0.3 allows remote attackers to execute arbitrary Javascript in other domains by using an IFRAME and causing the browser to navigate to a previous javascript: URL, which can lead to arbitrary code execution when combined with CVE-2005-1477.

Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to load local files via links "with a custom getter and toString method" that are middle-clicked by the user to be opened in a new tab.

Firefox 0.9, Thunderbird 0.6 and other versions before 0.9, and Mozilla 1.7 before 1.7.5 save temporary files with world-readable permissions, which allows local users to read certain web content or attachments that belong to other users, e.g. content that is managed by helper applications such as PDF.

Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL references a secure SSL site while an insecure page is being loaded, which could facilitate phishing attacks.

Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to obtain sensitive data from the clipboard via Javascript that generates a middle-click event on systems for which a middle-click performs a paste operation.

Firefox before 1.0 and Mozilla before 1.7.5, when configured to use a proxy, respond to 407 proxy auth requests from arbitrary servers, which allows remote attackers to steal NTLM or SPNEGO credentials.

Heap-based buffer overflow in GIF2.cpp in Firefox before 1.0.2, Mozilla before to 1.7.6, and Thunderbird before 1.0.2, and possibly other applications that use the same library, allows remote attackers to execute arbitrary code via a GIF image with a crafted Netscape extension 2 block and buffer size.

FireFox 1.0.1 and Mozilla before 1.7.6 do not sufficiently address all attack vectors for loading chrome files and hijacking drag and drop events, which allows remote attackers to execute arbitrary XUL code by tricking a user into dragging a scrollbar, a variant of CVE-2005-0527, aka "Firescrolling 2."

Firefox before 1.0.2 allows remote attackers to execute arbitrary code by tricking a user into saving a page as a Firefox sidebar panel, then using the sidebar panel to inject Javascript into a privileged page.

Firefox before 1.0.1 and Mozilla Suite before 1.7.6 use a predictable filename for the plugin temporary directory, which allows local users to delete arbitrary files of other users via a symlink attack on the plugtmp directory.

Firefox before 1.0.1 and Mozilla before 1.7.6, when displaying the HTTP Authentication dialog, do not change the focus to the tab that generated the prompt, which could facilitate spoofing and phishing attacks.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote malicious web sites to spoof the extensions of files to download via the Content-Disposition header, which could be used to trick users into downloading dangerous content.

Firefox before 1.0.1 and Mozilla before 1.7.6 does not restrict xsl:include and xsl:import tags in XSLT stylesheets to the current domain, which allows remote attackers to determine the existence of files on the local system.

The Form Fill feature in Firefox before 1.0.1 allows remote attackers to steal potentially sensitive information via an input control that monitors the values that are generated by the autocomplete capability.

The installation confirmation dialog in Firefox before 1.0.1, Thunderbird before 1.0.1, and Mozilla before 1.7.6 allows remote attackers to use InstallTrigger to spoof the hostname of the host performing the installation via a long "user:pass" sequence in the URL, which appears before the real hostname.

Firefox before 1.0.1 allows remote attackers to spoof the (1) security and (2) download modal dialog boxes, which could be used to trick users into executing script or downloading and executing a file, aka "Firespoofing."

Firefox before 1.0.3 and Mozilla Suite before 1.7.7, when blocking a popup, allows remote attackers to execute arbitrary code via a javascript: URL that is executed when the user selects the "Show javascript" option.

Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to execute arbitrary script in other domains via a setter function for a variable in the target domain, which is executed when the user visits that domain, aka "Cross-site scripting through global scope pollution."

The favicon functionality in Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to execute arbitrary code via a <LINK rel="icon"> tag with a javascript: URL in the href attribute, aka "Firelinking."
