Further techniques that built on the slipstream research combined with a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 85.

The WebGL implementation in Mozilla Firefox 4.x through 4.0.1 does not properly restrict read operations, which allows remote attackers to obtain sensitive information from GPU memory associated with an arbitrary process, or cause a denial of service (application crash), via unspecified vectors.

The content layout component in Mozilla Firefox 3.0 and 3.0.1 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted but well-formed web page that contains "a simple set of legitimate HTML tags."

Mozilla Firefox before 43.0 stores cookies containing vertical tab characters, which allows remote attackers to obtain sensitive information by reading HTTP Cookie headers.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox 4.x through 4.0.1 allows remote attackers to inject arbitrary web script or HTML via an SVG element containing an HTML-encoded entity.

Websites redirecting to a non-HTTP scheme URL could allow a website address to be spoofed for a malicious page This vulnerability affects Firefox for iOS < 136.

A mechanism to spoof the Firefox for Android addressbar using a "javascript:" URI. On Firefox for Android, the base domain is parsed incorrectly, making the resulting location less visibly a spoofed site and showing an incorrect domain in appended notifications. This vulnerability affects Firefox < 53.

Unspecified vulnerability in the JavaScript engine in Mozilla Firefox 3.5.x before 3.5.3 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple NSS NIST curves were susceptible to a side-channel attack known as "Minerva". This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.

Accessing a non-secure HTTP site that uses a non-existent port may cause the SSL padlock icon in the location URL bar to, misleadingly, appear secure. This vulnerability affects Firefox for iOS < 133.

Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1.

Memory safety bugs present in Firefox 152. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 153.

Buffer overflow in the mozilla::gfx::FilterSupport::ComputeSourceNeededRegions function in Mozilla Firefox before 49.0 allows remote attackers to execute arbitrary code by leveraging improper interaction between empty filters and CANVAS element rendering.

When downloading an HTML file, if the title of the page was formatted as a filename with a malicious extension, Firefox may have saved the file with that extension, leading to possible system compromise if the downloaded file was later ran. This vulnerability affects Firefox < 107.

Malicious scripts that interrupt new tab page loading could cause desynchronization between the address bar and page content, allowing the attacker to spoof arbitrary HTML under a trusted domain. This vulnerability affects Firefox for iOS < 147.2.1.

Mozilla developers and community members reported memory safety bugs present in Firefox 63. 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 < 64.

The "export" function in the Certificate Viewer can force local filesystem navigation when the "common name" in a certificate contains slashes, allowing certificate content to be saved in unsafe locations with an arbitrary filename. This vulnerability affects Firefox < 51.

Mozilla developers reported memory safety bugs present in Firefox 86. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 87.

Mozilla developers and community members reported memory safety bugs present in Firefox 77. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 78.

Integer overflow in the WebSocketChannel class in the WebSockets subsystem in Mozilla Firefox before 48.0 and Firefox ESR < 45.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted packets that trigger incorrect buffer-resize operations during buffering.
