Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, Thunderbird before 3.0.5, and SeaMonkey before 2.0.5 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Integer overflow in the XSLT node sorting implementation in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, Thunderbird before 3.0.5, and SeaMonkey before 2.0.5 allows remote attackers to execute arbitrary code via a large text value for a node.

Use-after-free vulnerability in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before 2.0.5, allows remote attackers to execute arbitrary code via vectors involving multiple plugin instances.

Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before 2.0.5, does not properly handle situations in which both "Content-Disposition: attachment" and "Content-Type: multipart" are present in HTTP headers, which allows remote attackers to conduct cross-site scripting (XSS) attacks via an uploaded HTML document.

Integer overflow in the nsGenericDOMDataNode::SetTextInternal function in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, Thunderbird before 3.0.5, and SeaMonkey before 2.0.5 allows remote attackers to execute arbitrary code via a DOM node with a long text value that triggers a heap-based buffer overflow.

Use-after-free vulnerability in the nsCycleCollector::MarkRoots function in Mozilla Firefox 3.5.x before 3.5.10 and SeaMonkey before 2.0.5 allows remote attackers to execute arbitrary code via a crafted HTML document, related to an improper frame construction process for menus.

The nsIScriptableUnescapeHTML.parseFragment method in the ParanoidFragmentSink protection mechanism in Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, Thunderbird before 3.1.8, and SeaMonkey before 2.0.12 does not properly sanitize HTML in a chrome document, which makes it easier for remote attackers to execute arbitrary JavaScript with chrome privileges via a javascript: URI in input to an extension, as demonstrated by a javascript:alert sequence in (1) the HREF attribute of an A element or (2) the ACTION attribute of a FORM element.

The XMLDocument::load function in Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 does not perform the expected nsIContentPolicy checks during loading of content by XML documents, which allows attackers to bypass intended access restrictions via crafted content.

Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, executes a mail application in situations where an IMG element has a SRC attribute that is a redirect to a mailto: URL, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many images.

Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response.

Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, does not prevent applets from interpreting mouse clicks as drag-and-drop actions, which allows remote attackers to execute arbitrary JavaScript with Chrome privileges by loading a chrome: URL and then loading a javascript: URL.

Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, frees the contents of the window.navigator.plugins array while a reference to an array element is still active, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors, related to a "dangling pointer vulnerability."

Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2; Thunderbird before 3.0.4; and SeaMonkey before 2.0.4 do not properly manage reference counts for option elements in a XUL tree optgroup, which might allow remote attackers to execute arbitrary code via unspecified vectors that trigger access to deleted elements, related to a "dangling pointer vulnerability."

Use-after-free vulnerability in the nsTreeSelection implementation in Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.9, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors that trigger a call to the handler for the select event for XUL tree items.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.19, 3.5.x before 3.5.9, and 3.6.x before 3.6.2; Thunderbird before 3.0.4; and SeaMonkey before 2.0.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, Thunderbird before 3.0.4, and SeaMonkey before 2.0.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The JavaScript implementation in Mozilla Firefox 3.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before 2.0.5, allows remote attackers to send selected keystrokes to a form field in a hidden frame, instead of the intended form field in a visible frame, via certain calls to the focus method.

Mozilla Thunderbird before 2.0.0.24 and SeaMonkey before 1.1.19 process e-mail attachments with a parser that performs casts and line termination incorrectly, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted message, related to message indexing.

The nsAuthSSPI::Unwrap function in extensions/auth/nsAuthSSPI.cpp in Mozilla Thunderbird before 2.0.0.24 and SeaMonkey before 1.1.19 on Windows Vista, Windows Server 2008 R2, and Windows 7 allows remote SMTP, IMAP, and POP servers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via crafted data in a session that uses SSPI.

The mail component in Mozilla SeaMonkey before 1.1.19 does not properly restrict execution of scriptable plugin content, which allows user-assisted remote attackers to obtain sensitive information via crafted content in an IFRAME element in an HTML e-mail message, as demonstrated by a Flash object that sends arbitrary local files during a reply or forward operation.
