Mozilla Firefox executes DOM calls in response to a javascript: URI in the target attribute of a submit element within a form contained in an inline PDF file, which might allow remote attackers to bypass intended Adobe Acrobat JavaScript restrictions on accessing the document object, as demonstrated by a web site that permits PDF uploads by untrusted users, and therefore has a shared document.domain between the web site and this javascript: URI. NOTE: the researcher reports that Adobe's position is "a PDF file is active content."

Mozilla Firefox before 3.0.14 does not properly implement certain dialogs associated with the (1) pkcs11.addmodule and (2) pkcs11.deletemodule operations, which makes it easier for remote attackers to trick a user into installing or removing an arbitrary PKCS11 module.

Mozilla Firefox before 3.0.10 processes a 3xx HTTP CONNECT response before a successful SSL handshake, which allows man-in-the-middle attackers to execute arbitrary web script, in an https site's context, by modifying this CONNECT response to specify a 302 redirect to an arbitrary https web site.

The nsTextFrame::ClearTextRun function in layout/generic/nsTextFrameThebes.cpp in Mozilla Firefox 3.0.9 allows remote attackers to cause a denial of service (memory corruption) and probably execute arbitrary code via unspecified vectors.

If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute updater.exe from the install location with system privileges. Although the Mozilla Maintenance Service does ensure that updater.exe is signed by Mozilla, the version could have been rolled back to a previous version which would have allowed exploitation of an older bug and arbitrary code execution with System Privileges. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, and Firefox ESR < 78.2.
