On Linux systems, if the content process is compromised, the sandbox broker will allow files to be truncated even though the sandbox explicitly only has read access to the local file system and no write permissions. Note: This attack only affects the Linux operating system. Other operating systems are not affected. This vulnerability affects Firefox < 55.

Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.5 allow remote attackers to execute arbitrary code via a crafted XPCNativeWrapper.

Spoofing issue in the Toolbar component in Firefox for Android. This vulnerability was fixed in Firefox 151.

Mozilla developers and community members Calixte Denizet, Gabriele Svelto, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 110. 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 < 111.

Firefox 1.0.6 allows attackers to cause a denial of service (crash) via a Proxy Auto-Config (PAC) script that uses an eval statement. NOTE: it is not clear whether an untrusted party has any role in triggering this issue, so it might not be a vulnerability.

Spoofing issue in Firefox. This vulnerability affects Firefox < 145, Firefox ESR < 140.5, and Firefox ESR < 115.30.

Mozilla developers reported memory safety bugs present in Firefox 88. 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 < 89.

Content Security Policy combined with HTTP to HTTPS redirection can be used by malicious server to verify whether a known site is within a user's browser history. This vulnerability affects Firefox < 50.

The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms. This vulnerability affects Firefox ESR < 52.7.2 and Firefox < 59.0.1.

Firefox 1.0 does not invoke the Javascript Security Manager when a user drags a javascript: or data: URL to a tab, which allows remote attackers to bypass the security model, aka "firetabbing."

The Mozilla Maintenance Service can be invoked by an unprivileged user to read 32 bytes of any arbitrary file on the local system by convincing the service that it is reading a status file provided by the Mozilla Windows Updater. The Mozilla Maintenance Service executes with privileged access, bypassing system protections against unprivileged users. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.

Mozilla Firefox 3 before 3.0.11 associates an incorrect principal with a file: URL loaded through the location bar, which allows user-assisted remote attackers to bypass intended access restrictions and read files via a crafted HTML document, aka a "file-URL-to-file-URL scripting" attack.

An issue with incorrect ownership model of "privateBrowsing" information exposed through developer tools. This can result in a non-exploitable crash when manually triggered during debugging. This vulnerability affects Firefox < 53.

If an attacker needed a user to load an insecure http: page and knew that user had enabled HTTPS-only mode, the attacker could have tricked the user into clicking to grant an HTTPS-only exception if they could get the user to participate in a clicking game. This vulnerability affects Firefox < 120.

Same-origin policy bypass in the DOM: Workers component. This vulnerability affects Firefox < 145 and Firefox ESR < 140.5.

Undefined behavior in the WebRTC: Signaling component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9.

JIT miscompilation in the JavaScript Engine component. This vulnerability affects Firefox < 149 and Firefox ESR < 140.9.

The PRNG implementation in the DNS resolver in Mozilla Firefox (aka Fennec) before 37.0 on Android does not properly generate random numbers for query ID values and UDP source ports, which makes it easier for remote attackers to spoof DNS responses by guessing these numbers, a related issue to CVE-2012-2808.

JIT miscompilation in the JavaScript Engine: JIT component. This vulnerability affects Firefox < 145.

Mozilla Firefox 3.6.3 on Windows XP SP3 allows remote attackers to cause a denial of service (memory consumption and application crash) via JavaScript code that creates multiple arrays containing elements with long string values, and then appends long strings to the content of a P element, related to the gfxWindowsFontGroup::MakeTextRun function in xul.dll, a different vulnerability than CVE-2009-1571.
