The lifecycle of IPC Actors allows managed actors to outlive their manager actors; and the former must ensure that they are not attempting to use a dead actor they have a reference to. Such a check was omitted in WebGL, resulting in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 84.

Mozilla Firefox 1.5.0.6 allows remote attackers to execute arbitrary JavaScript in the context of the browser's session with an arbitrary intranet web server, by hosting script on an Internet web server that can be made inaccessible by the attacker and that has a domain name under the attacker's control, which can force the browser to drop DNS pinning and perform a new DNS query for the domain name after the script is already running.

Mozilla developers reported memory safety bugs present in Firefox 81. 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 < 82.

Mozilla developers and community members reported memory safety bugs present in Firefox 75. 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 < 76.

The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox escape. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8 and Firefox < 76.

This affects the package convict before 6.2.3. This is a bypass of [CVE-2022-22143](https://security.snyk.io/vuln/SNYK-JS-CONVICT-2340604). The [fix](https://github.com/mozilla/node-convict/commit/3b86be087d8f14681a9c889d45da7fe3ad9cd880) introduced, relies on the startsWith method and does not prevent the vulnerability: before splitting the path, it checks if it starts with __proto__ or this.constructor.prototype. To bypass this check it's possible to prepend the dangerous paths with any string value followed by a dot, like for example foo.__proto__ or foo.this.constructor.prototype.

The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox escape. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8 and Firefox < 76.

Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 improperly follow the CORS cross-origin request algorithm for the POST method in situations involving an unspecified Content-Type header manipulation, which allows remote attackers to bypass the Same Origin Policy by leveraging the lack of a preflight-request step.

The accessibility-tools feature in Mozilla Firefox before 42.0 on OS X improperly interacts with the implementation of the TABLE element, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code by using an NSAccessibilityIndexAttribute value to reference a row index.

The ReadbackResultWriterD3D11::Run function in Mozilla Firefox before 41.0 and Firefox ESR 38.x before 38.3 misinterprets the return value of a function call, which might allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unknown vectors.

The (1) AddWeightedPathSegLists and (2) SVGPathSegListSMILType::Interpolate functions in Mozilla Firefox before 42.0 and Firefox ESR 38.x before 38.4 lack status checking, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted SVG document.
