CVE-2016-9079

A use-after-free vulnerability in SVG Animation has been discovered. An exploit built on this vulnerability has been discovered in the wild targeting Firefox and Tor Browser users on Windows. This vulnerability affects Firefox 50.0.2, Firefox ESR 45.5.1, and Thunderbird 45.5.1...

CVE-2016-9078

Redirection from an HTTP connection to a "data:" URL assigns the referring site's origin to the "data:" URL in some circumstances. This can result in same-origin violations against a domain if it loads resources from malicious sites. Cross-origin setting of cookies has been demonstrated without t...

CVE-2016-9895

Event handlers on "marquee" elements were executed despite a strict Content Security Policy CSP that disallowed inline JavaScript. This vulnerability affects Firefox 50.1, Firefox ESR 45.6, and Thunderbird 45.6...

CVE-2016-9070

A maliciously crafted page loaded to the sidebar through a bookmark can reference a privileged chrome window and engage in limited JavaScript operations violating cross-origin protections. This vulnerability affects Firefox 50...

Cross site scripting

Control characters prepended before "javascript:" URLs pasted in the addressbar can cause the leading characters to be ignored and the pasted JavaScript to be executed instead of being blocked. This could be used in social engineering and self-cross-site-scripting self-XSS attacks where users are...

Code injection

Some Arabic and Indic vowel marker characters can be combined with Latin characters in a domain name to eclipse the non-Latin character with some font sets on the addressbar. The non-Latin character will not be visible to most viewers. This allows for domain spoofing attacks because these combine...

Design/Logic Flaw

If the "app.support.baseURL" preference is changed by a malicious local program to contain HTML and script content, this content is not sanitized. It will be executed if a user loads "chrome://browser/content/preferences/in-content/preferences.xul" directly in a tab and executes a search. This...

Code injection

If manipulated hyperlinked text with "chrome:" URL contained in it is dragged and dropped on the "home" icon, the home page can be reset to include a normally-unlinkable chrome page as one of the home page tabs. This vulnerability affects Firefox 60...

Memory corruption

Memory safety bugs were reported in Firefox 50.0.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox 50.1...

Cross site scripting

Response header name interning does not have same-origin protections and these headers are stored in a global registry. This allows stored header names to be available cross-origin. This vulnerability affects Firefox 55...

Spoofing

A maliciously crafted page loaded to the sidebar through a bookmark can reference a privileged chrome window and engage in limited JavaScript operations violating cross-origin protections. This vulnerability affects Firefox 50...

CVE-2016-5291

A same-origin policy bypass with local shortcut files to load arbitrary local content from disk. This vulnerability affects Thunderbird 45.5, Firefox ESR 45.5, and Firefox 50...

Design/Logic Flaw

A STUN server in conjunction with a large number of "webkitRTCPeerConnection" objects can be used to send large STUN packets in a short period of time due to a lack of rate limiting being applied on e10s systems, allowing for a denial of service attack. This vulnerability affects Firefox 51...

Spoofing

Data sent with in multipart channels, such as the multipart/x-mixed-replace MIME type, will ignore the referrer-policy response header, leading to potential information disclosure for sites using this header. This vulnerability affects Firefox 51...

Design/Logic Flaw

The cache directory on the local file system is set to be world writable. Firefox defaults to extracting libraries from this cache. This allows for the possibility of an installed malicious application or tools with write access to the file system to replace files used by Firefox with their own...

Cross site scripting

JavaScript can be injected into an exported bookmarks file by placing JavaScript code into user-supplied tags in saved bookmarks. If the resulting exported HTML file is later opened in a browser this JavaScript will be executed. This could be used in social engineering and self-cross-site-scripti...

CVE-2018-5108

CVE-2018-5108 is a Firefox Blob URL information-leak vulnerability. A Blob URL can violate origin attribute segregation, permitting data exchange between a private browsing context and a normal tab, enabling leakage of private information from the private context. Public documentation notes the a...
