The nsDocument::MaybePreLoadImage function in content/base/src/nsDocument.cpp in the image-preloading implementation in Mozilla Firefox 3.6 before 3.6.2 does not apply scheme restrictions and policy restrictions to the image's URL, which might allow remote attackers to cause a denial of service (application crash or hang) or hijack the functionality of the browser's add-ons via a crafted SRC attribute of an IMG element, as demonstrated by remote command execution through an ssh: URL in a configuration that supports gnome-vfs with a nonstandard network.gnomevfs.supported-protocols setting.

The browser engine in Mozilla Firefox 3.0.x before 3.0.18, 3.5.x before 3.5.8, and 3.6.x before 3.6.2; Thunderbird before 3.0.2; and SeaMonkey before 2.0.3 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via vectors related to (1) layout/generic/nsBlockFrame.cpp and (2) the _evaluate function in modules/plugin/base/src/nsNPAPIPlugin.cpp.

The gfxTextRun::SanitizeGlyphRuns function in gfx/thebes/src/gfxFont.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 on Mac OS X, when the Core Text API is used, does not properly perform certain deletions, which allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via an HTML document containing invisible Unicode characters, as demonstrated by the U+FEFF, U+FFF9, U+FFFA, and U+FFFB characters.

The TraceRecorder::traverseScopeChain function in js/src/jstracer.cpp in the browser engine in Mozilla Firefox 3.6 before 3.6.2 allows remote attackers to cause a denial of service (memory corruption and application crash) and possibly execute arbitrary code via vectors involving certain indirect calls to the JavaScript eval function.

Use-after-free vulnerability in the imgContainer::InternalAddFrameHelper function in src/imgContainer.cpp in libpr0n in Mozilla Firefox 3.6 before 3.6.2 allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via a multipart/x-mixed-replace animation in which the frames have different bits-per-pixel (bpp) values.

Integer overflow in the decompression functionality in the Web Open Fonts Format (WOFF) decoder in Mozilla Firefox 3.6 before 3.6.2 and 3.7 before 3.7 alpha 3 allows remote attackers to execute arbitrary code via a crafted WOFF file that triggers a buffer overflow, as demonstrated by the vd_ff module in VulnDisco 9.0.

Mozilla Necko, as used in Firefox, SeaMonkey, and other applications, performs DNS prefetching of domain names contained in links within local HTML documents, which makes it easier for remote attackers to determine the network location of the application's user by logging DNS requests. NOTE: the vendor disputes the significance of this issue, stating "I don't think we necessarily need to worry about that case."

Visual truncation vulnerability in the MakeScriptDialogTitle function in nsGlobalWindow.cpp in Mozilla Firefox allows remote attackers to spoof the origin domain name of a script via a long name.

Race condition in Mozilla Firefox allows remote attackers to produce a JavaScript message with a spoofed domain association by writing the message in between the document request and document load for a web page in a different domain.

Unspecified vulnerability in Wikipedia Toolbar extension before 0.5.9.2 for Firefox allows user-assisted remote attackers to execute arbitrary JavaScript with Chrome privileges via vectors involving unspecified Toolbar buttons and the eval function. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Sage 1.4.3 and earlier extension for Firefox performs certain operations with chrome privileges, which allows remote attackers to execute arbitrary commands and perform cross-domain scripting attacks via the description tag of an RSS feed.

infoRSS 1.1.4.2 and earlier extension for Firefox performs certain operations with chrome privileges, which allows remote attackers to execute arbitrary commands and perform cross-domain scripting attacks via the description tag of an RSS feed.

Yoono extension before 6.1.1 for Firefox performs certain operations with chrome privileges, which allows user-assisted remote attackers to execute arbitrary commands and perform cross-domain scripting attacks via DOM event handlers such as onload.

Argument injection vulnerability in (1) src/content/js/connection/sftp.js and (2) src/content/js/connection/controlSocket.js.in in FireFTP Extension 1.0.5 for Firefox allows remote authenticated SFTP users to cause victims to alter permissions, delete, download, or move the wrong file via a filename containing " (double quotes), which is not properly filtered or encoded when FireFTP constructs the command to send to psftp.exe.

Heap-based buffer overflow in a regular-expression parser in Mozilla Network Security Services (NSS) before 3.12.3, as used in Firefox, Thunderbird, SeaMonkey, Evolution, Pidgin, and AOL Instant Messenger (AIM), allows remote SSL servers to cause a denial of service (application crash) or possibly execute arbitrary code via a long domain name in the subject's Common Name (CN) field of an X.509 certificate, related to the cert_TestHostName function.

The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.

Mozilla Firefox before 3.0.12 does not properly handle an SVG element that has a property with a watch function and an __defineSetter__ function, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted document, related to a certain pointer misinterpretation.

Worldweaver DX Studio Player 3.0.29.0, 3.0.22.0, 3.0.12.0, and probably other versions before 3.0.29.1, when used as a plug-in for Firefox, does not restrict access to the shell.execute JavaScript API method, which allows remote attackers to execute arbitrary commands via a .dxstudio file that invokes this method.

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."

The Math.random function in the JavaScript implementation in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before 2.0.5, uses a random number generator that is seeded only once per browser session, which makes it easier for remote attackers to track a user, or trick a user into acting upon a spoofed pop-up message, by calculating the seed value, related to a "temporary footprint" and an "in-session phishing attack."
