Inappropriate implementation in cache in Google Chrome prior to 81.0.4044.92 allowed a remote attacker to leak cross-origin data via a crafted HTML page.

Insufficient data validation in loader in Google Chrome prior to 83.0.4103.61 allowed a remote attacker who had been able to write to disk to leak cross-origin data via a crafted HTML page.

Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. *This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.

In Libgcrypt 1.8.4, the C implementation of AES is vulnerable to a flush-and-reload side-channel attack because physical addresses are available to other processes. (The C implementation is used on platforms where an assembly-language implementation is unavailable.) NOTE: the vendor's position is that the issue report cannot be validated because there is no description of an attack

The txXPathNodeUtils::getXSLTId function in txMozillaXPathTreeWalker.cpp and txStandaloneXPathTreeWalker.cpp in Mozilla Firefox before 3.5.19, 3.6.x before 3.6.17, and 4.x before 4.0.1, and SeaMonkey before 2.0.14, allows remote attackers to obtain potentially sensitive information about heap memory addresses via an XML document containing a call to the XSLT generate-id XPath function.

The layout engine in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 executes different code for visited and unvisited links during the processing of Cascading Style Sheets (CSS) token sequences, which makes it easier for remote attackers to obtain sensitive information about visited web pages via a timing attack.

WebExtension content scripts can be loaded into about: pages in some circumstances, in violation of the permissions granted to extensions. This could allow an extension to interfere with the loading and usage of these pages and use capabilities that were intended to be restricted from extensions. This vulnerability affects Firefox < 64.

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 do not properly restrict read access to the statusText property of XMLHttpRequest objects, which allows remote attackers to discover the existence of intranet web servers via cross-origin requests.

Mozilla Firefox before 3.6.7 and Thunderbird before 3.1.1 do not properly implement read restrictions for CANVAS elements, which allows remote attackers to obtain sensitive cross-origin information via vectors involving reference retention and node deletion.

The importScripts Web Worker method in Mozilla Firefox 3.5.x before 3.5.11 and 3.6.x before 3.6.7, Thunderbird 3.0.x before 3.0.6 and 3.1.x before 3.1.1, and SeaMonkey before 2.0.6 does not verify that content is valid JavaScript code, which allows remote attackers to bypass the Same Origin Policy and obtain sensitive information via a crafted HTML document.

Mozilla Firefox, possibly before 3.6, allows remote attackers to discover a redirect's target URL, for the session of a specific user of a web site, by placing the site's URL in the HREF attribute of a stylesheet LINK element, and then reading the document.styleSheets[0].href property value, related to an IFRAME element.

Cross-origin images can be read from a canvas element in violation of the same-origin policy using the transferFromImageBitmap method. *Note: This only affects Firefox 65. Previous versions are unaffected.*. This vulnerability affects Firefox < 65.0.1.

Bugzilla before 3.0.11, 3.2.x before 3.2.6, 3.4.x before 3.4.5, and 3.5.x before 3.5.3 does not block access to files and directories that are used by custom installations, which allows remote attackers to obtain sensitive information via requests for (1) CVS/, (2) contrib/, (3) docs/en/xml/, (4) t/, or (5) old-params.txt.

Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects Firefox < 64.

content/html/document/src/nsHTMLDocument.cpp in Mozilla Firefox 3.0.x before 3.0.15 and 3.5.x before 3.5.4 allows user-assisted remote attackers to bypass the Same Origin Policy and read an arbitrary content selection via the document.getSelection function.

WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.

browser/ui/website_settings/website_settings.cc in Google Chrome before 42.0.2311.90 does not always display "Media: Allowed by you" in a Permissions table after the user has granted camera permission to a web site, which might make it easier for user-assisted remote attackers to obtain sensitive video data from a device's physical environment via a crafted web site that turns on the camera at a time when the user believes that camera access is prohibited.

The default configuration for the Xerces SAX Parser in Castor before 1.3.3 allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XML document.

Mozilla Firefox before 38.0 does not recognize a referrer policy delivered by a referrer META element in cases of context-menu navigation and middle-click navigation, which allows remote attackers to obtain sensitive information by reading web-server Referer logs that contain private data in a URL, as demonstrated by a private path component.

Mozilla Firefox before 3.0.9 and SeaMonkey before 1.1.17 allow user-assisted remote attackers to obtain sensitive information via a web page with an embedded frame, which causes POST data from an outer page to be sent to the inner frame's URL during a SAVEMODE_FILEONLY save of the inner frame.

When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS 1.3.

Decrypted S/MIME parts, when included in HTML crafted for an attack, can leak plaintext when included in a a HTML reply/forward. This vulnerability affects Thunderbird < 52.9.

Service workers can use redirection to avoid the tainting of cross-origin resources in some instances, allowing a malicious site to read responses which are supposed to be opaque. This vulnerability affects Firefox < 61.

A compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

dDecrypted S/MIME parts hidden with CSS or the plaintext HTML tag can leak plaintext when included in a HTML reply/forward. This vulnerability affects Thunderbird < 52.9.

Other operating systems are unaffected.*. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.

In the previous mitigations for Spectre, the resolution or precision of various methods was reduced to counteract the ability to measure precise time intervals. In that work PerformanceNavigationTiming was not adjusted but it was found that it could be used as a precision timer. This vulnerability affects Thunderbird < 60, Firefox ESR < 60.1, and Firefox < 61.

An invalid grid size during QCMS (color profile) transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.

Mozilla Firefox before 31.1 on Android does not properly restrict copying of local files onto the SD card during processing of file: URLs, which allows attackers to obtain sensitive information from the Firefox profile directory via a crafted application. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-1515.

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.
