The jar: URI implementation in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey does not follow the Content-Disposition header of the inner URI, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via an uploaded .jar file with a "Content-Disposition: attachment" designation.

Mozilla Firefox before 3.0.9 and SeaMonkey 1.1.17 do not block javascript: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header or (2) specifying the content of a Refresh header. NOTE: it was later reported that Firefox 3.6 a1 pre and Mozilla 1.7.x and earlier are also affected.

Google Chrome before 42.0.2311.90 does not properly consider the interaction of page navigation with the handling of touch events and gesture events, which allows remote attackers to trigger unintended UI actions via a crafted web site that conducts a "tapjacking" attack.

The RuntimeEventRouter::OnExtensionUninstalled function in extensions/browser/api/runtime/runtime_api.cc in Google Chrome before 45.0.2454.85 does not ensure that the setUninstallURL preference corresponds to the URL of a web site, which allows user-assisted remote attackers to trigger access to an arbitrary URL via a crafted extension that is uninstalled.

The Public Key Pinning (PKP) implementation in Mozilla Firefox before 33.0 does not properly consider the connection-coalescing behavior of SPDY and HTTP/2 in the case of a shared IP address, which allows man-in-the-middle attackers to bypass an intended pinning configuration and spoof a web site by providing a valid certificate from an arbitrary recognized Certification Authority.

Google Chrome 1.0.154.43 allows remote attackers to trick a user into visiting an arbitrary URL via an onclick action that moves a crafted element to the current mouse position, related to a "Clickjacking" vulnerability. NOTE: a third party disputes the relevance of this issue, stating that "every sufficiently featured browser is and likely will remain susceptible to the behavior known as clickjacking," and adding that the exploit code "is not a valid demonstration of the issue.

Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre does not properly block data: URIs in Location headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Location header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Location header. NOTE: the JavaScript executes outside of the context of the HTTP site.

The Public Key Pinning (PKP) implementation in Mozilla Firefox before 33.0 skips pinning checks upon an unspecified issuer-verification error, which makes it easier for remote attackers to bypass an intended pinning configuration and spoof a web site via a crafted certificate that leads to presentation of the Untrusted Connection dialog to the user.

The docshell implementation in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to trigger the loading of a URL with a spoofed baseURI property, and conduct cross-site scripting (XSS) attacks, via a crafted web site that performs history navigation.

In all Android releases from CAF using the Linux kernel, some regions of memory were not protected during boot.

When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.

Cross-site scripting (XSS) vulnerability in the DocumentLoader::maybeCreateArchive function in core/loader/DocumentLoader.cpp in Blink, as used in Google Chrome before 35.0.1916.114, allows remote attackers to inject arbitrary web script or HTML via crafted MHTML content, aka "Universal XSS (UXSS)."

Previously, this document's URL (as reported by the document.location property, for example) was the originating javascript: URL which could lead to spoofing attacks; it is now correctly the URL of the originating document. This vulnerability affects Firefox < 74.
