CVE-2017-5451 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
A mechanism to spoof the addressbar through the user interaction on the addressbar and the "onblur" event. The event could be used by script to affect text display to make the loaded site appear to be different from the one actually loaded within the addressbar. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-5449 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
A possibly exploitable crash triggered during layout and manipulation of bidirectional unicode text in concert with CSS animations. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-7843 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Enterprise Linux and 5 more 2025-11-25 N/A
When Private Browsing mode is used, it is possible for a web worker to write persistent data to IndexedDB and fingerprint a user uniquely. IndexedDB should not be available in Private Browsing mode and this stored data will persist across multiple private browsing mode sessions because it is not cleared when exiting. This vulnerability affects Firefox ESR < 52.5.2 and Firefox < 57.0.1.
CVE-2017-5454 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
A mechanism to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2018-12387 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 N/A
A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.
CVE-2018-12397 4 Canonical, Debian, Mozilla and 1 more 8 Ubuntu Linux, Debian Linux, Firefox and 5 more 2025-11-25 N/A
A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-12367 3 Canonical, Debian, Mozilla 4 Ubuntu Linux, Debian Linux, Firefox and 1 more 2025-11-25 N/A
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.
CVE-2016-5293 3 Debian, Microsoft, Mozilla 3 Debian Linux, Windows, Firefox 2025-11-25 N/A
When the Mozilla Updater is run, if the Updater's log file in the working directory points to a hardlink, data can be appended to an arbitrary local file. This vulnerability requires local system access. Note: this issue only affects Windows operating systems. This vulnerability affects Firefox ESR < 45.5 and Firefox < 50.
CVE-2017-7830 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5.
CVE-2017-7825 3 Apple, Debian, Mozilla 4 Mac Os X, Debian Linux, Firefox and 1 more 2025-11-25 N/A
Several fonts on OS X display some Tibetan and Arabic characters as whitespace. When used in the addressbar as part of an IDN this can be used for domain name spoofing attacks. Note: This attack only affects OS X operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2017-7768 2 Microsoft, Mozilla 2 Windows, Firefox 2025-11-25 N/A
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.
CVE-2017-7765 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 N/A
The "Mark of the Web" was not correctly saved on Windows when files with very long names were downloaded from the Internet. Without the Mark of the Web data, the security warning that Windows displays before running executables downloaded from the Internet is not shown. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-7764 3 Debian, Mozilla, Redhat 4 Debian Linux, Firefox, Thunderbird and 1 more 2025-11-25 N/A
Characters from the "Canadian Syllabics" unicode block can be mixed with characters from other unicode blocks in the addressbar instead of being rendered as their raw "punycode" form, allowing for domain name spoofing attacks through character confusion. The current Unicode standard allows characters from "Aspirational Use Scripts" such as Canadian Syllabics to be mixed with Latin characters in the "moderately restrictive" IDN profile. We have changed Firefox behavior to match the upcoming Unicode version 10.0 which removes this category and treats them as "Limited Use Scripts.". This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-5383 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
CVE-2017-5378 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
CVE-2016-9074 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2025-11-25 N/A
An existing mitigation of timing side-channel attacks is insufficient in some circumstances. This issue is addressed in Network Security Services (NSS) 3.26.1. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2016-5294 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 N/A
The Mozilla Updater can be made to choose an arbitrary target working directory for output files resulting from the update process. This vulnerability requires local system access. Note: this issue only affects Windows operating systems. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2016-5291 3 Debian, Mozilla, Redhat 4 Debian Linux, Firefox, Thunderbird and 1 more 2025-11-25 N/A
A same-origin policy bypass with local shortcut files to load arbitrary local content from disk. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2013-5593 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 N/A
The SELECT element implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly restrict the nature or placement of HTML within a dropdown menu, which allows remote attackers to spoof the address bar or conduct clickjacking attacks via vectors that trigger navigation off of a page containing this element.
CVE-2016-9904 3 Debian, Mozilla, Redhat 7 Debian Linux, Firefox, Thunderbird and 4 more 2025-11-25 N/A
An attacker could use a JavaScript Map/Set timing attack to determine whether an atom is used by another compartment/zone in specific contexts. This could be used to leak information, such as usernames embedded in JavaScript code, across websites. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
