The HTTP Alternative Services header, Alt-Svc, can be used by a malicious site to scan all TCP ports of any host that the accessible to a user when web content is loaded. This vulnerability affects Firefox < 68.

By tricking the browser with a `X-Frame-Options` header, a sandboxed iframe could have presented a button that, if clicked by a user, would bypass restrictions to open a new window. This vulnerability affects Firefox < 127, Firefox ESR < 115.12, and Thunderbird < 115.12.

Race condition in permission assignment

During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox < 80 and Firefox for Android < 80.

Upon scanning a JavaScript URI with the QR code scanner, an attacker could have executed unauthorized scripts on the current top origin sites in the URL bar. This vulnerability affects Firefox for iOS < 123.

On Windows systems, the logger run by the Windows updater deletes the file "update.log" before it runs in order to write a new log of that name. The path to this file is supplied at the command line to the updater and could be used in concert with another local exploit to delete a different file named "update.log" instead of the one intended. Note: This attack only affects Windows operating systems. Other operating systems are not affected. This vulnerability affects Firefox < 55.

When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.

The Updater in Mozilla Firefox before 48.0 on Windows allows local users to write to arbitrary files via vectors involving the callback application-path parameter and a hard link.

mar_read.c in the Updater in Mozilla Firefox before 40.0 and Firefox ESR 38.x before 38.2 allows local users to gain privileges or cause a denial of service (out-of-bounds write) via a crafted name of a Mozilla Archive (aka MAR) file.

NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.

During RSA key generation, bignum implementations used a variation of the Binary Extended Euclidean Algorithm which entailed significantly input-dependent flow. This allowed an attacker able to perform electromagnetic-based side channel attacks to record traces leading to the recovery of the secret primes. *Note:* An unmodified Firefox browser does not generate RSA keys in normal operation and is not affected, but products built on top of it might. This vulnerability affects Firefox < 78.

The update implementation in Mozilla Firefox before 38.0 on Windows does not ensure that the pathname for updater.exe corresponds to the application directory, which might allow local users to gain privileges via a Trojan horse file.

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.

The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.

Argument injection vulnerability in Microsoft Internet Explorer, when running on systems with Firefox installed and certain URIs registered, allows remote attackers to conduct cross-browser scripting attacks and execute arbitrary commands via shell metacharacters in a (1) FirefoxURL or (2) FirefoxHTML URI, which are inserted into the command line that is created when invoking firefox.exe. NOTE: it has been debated as to whether the issue is in Internet Explorer or Firefox. As of 20070711, it is CVE's opinion that IE appears to be failing to properly delimit the URL argument when invoking Firefox, and this issue could arise with other protocol handlers in IE as well. However, Mozilla has stated that it will address the issue with a "defense in depth" fix that will "prevent IE from sending Firefox malicious data."

CRLF injection vulnerability in the Digest Authentication support for Mozilla Firefox before 2.0.0.8 and SeaMonkey before 1.1.5 allows remote attackers to conduct HTTP request splitting attacks via LF (%0a) bytes in the username attribute.

The Chrome Object Wrapper (COW) implementation in Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 does not prevent acquisition of chrome privileges during calls to content level constructors, which allows remote attackers to bypass certain read-only restrictions and conduct cross-site scripting (XSS) attacks via a crafted web site.

Directory traversal vulnerability in Mozilla Firefox before 2.0.0.12, Thunderbird before 2.0.0.12, and SeaMonkey before 1.1.8, when using "flat" addons, allows remote attackers to read arbitrary Javascript, image, and stylesheet files via the chrome: URI scheme, as demonstrated by stealing session information from sessionstore.js.

Cross-site scripting (XSS) vulnerability in Adobe Flash Player before 9.0.277.0 and 10.x before 10.1.53.64, and Adobe AIR before 2.0.2.12610, when Firefox or Chrome is used, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to URL parsing.

Mozilla Firefox 3.0.10 and earlier on Linux allows remote attackers to cause a denial of service (application crash) via a URI for a large GIF image in the BACKGROUND attribute of a BODY element.

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.

Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 do not properly initialize memory for GIF rendering, which allows remote attackers to obtain sensitive information from process memory via crafted web script that interacts with a CANVAS element associated with a malformed GIF image.

Adobe Flash Player 9.0.124.0 and earlier, when a Mozilla browser is used, does not properly interpret jar: URLs, which allows attackers to obtain sensitive information via unknown vectors.

Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value.

Multiple cross-site scripting (XSS) vulnerabilities in the rendering engine in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allow remote attackers to inject arbitrary web script or HTML via (1) x-mac-arabic, (2) x-mac-farsi, or (3) x-mac-hebrew characters that may be converted to angle brackets during rendering.

Directory traversal vulnerability in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 on Linux allows remote attackers to read arbitrary files via a .. (dot dot) and URL-encoded / (slash) characters in a resource: URI.

Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow remote attackers to bypass cross-site scripting (XSS) protection mechanisms and conduct XSS attacks via byte order mark (BOM) characters that are removed from JavaScript code before execution, aka "Stripped BOM characters bug."

The js_dtoa function in Mozilla Firefox 2.x before 2.0.0.1, 1.5.x before 1.5.0.9, Thunderbird before 1.5.0.9, and SeaMonkey before 1.0.7 overwrites memory instead of exiting when the floating point precision is reduced, which allows remote attackers to cause a denial of service via any plugins that reduce the precision.

Mozilla Firefox 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to inject arbitrary Javascript into other sites by (1) "using a modal alert to suspend an event handler while a new page is being loaded", (2) using eval(), and using certain variants involving (3) "new Script;" and (4) using window.__proto__ to extend eval, aka "cross-site JavaScript injection".

Mozilla Firefox before 2.0.0.12 and Thunderbird before 2.0.0.12 does not properly manage a delay timer used in confirmation dialogs, which might allow remote attackers to trick users into confirming an unsafe action, such as remote file execution, by using a timer to change the window focus, aka the "dialog refocus bug" or "ffclick2".

The SVG filter implementation in Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 allows remote attackers to read pixel values, and possibly bypass the Same Origin Policy and read text from a different domain, by observing timing differences in execution of filter code.

Mozilla Network Security Services (NSS) before 3.19.1, as used in Mozilla Firefox before 39.0, Firefox ESR 31.x before 31.8 and 38.x before 38.1, and other products, does not properly perform Elliptical Curve Cryptography (ECC) multiplications, which makes it easier for remote attackers to spoof ECDSA signatures via unspecified vectors.

Multiple vulnerabilities in Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allow remote attackers to cause a denial of service (crash) via crafted HTML that triggers memory corruption or assert errors.

Multiple vulnerabilities in the Javascript engine in Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allow remote attackers to cause a denial of service (crash) via crafted HTML that triggers memory corruption.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 26.0 and SeaMonkey before 2.23 makes it easier for remote attackers to inject arbitrary web script or HTML by leveraging a Same Origin Policy violation triggered by lack of a charset parameter in a Content-Type HTTP header.

Mozilla Firefox before 26.0 and SeaMonkey before 2.23 on Linux allow user-assisted remote attackers to read clipboard data by leveraging certain middle-click paste operations.
