CVE-2020-26965 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26961 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26960 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26959 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26958 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26956 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26953 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 4.3 Medium
It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26951 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26950 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR < 78.4.1, and Thunderbird < 78.4.2.
CVE-2020-15685 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel Eus 2024-11-21 8.8 High
During the plaintext phase of the STARTTLS connection setup, protocol commands could have been injected and evaluated within the encrypted session. This vulnerability affects Thunderbird < 78.7.
CVE-2020-15683 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 9.8 Critical
Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3. 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 ESR < 78.4, Firefox < 82, and Thunderbird < 78.4.
CVE-2020-15678 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in a potential use-after-free. This occurs because the function APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15677 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 6.1 Medium
By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15676 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 6.1 Medium
Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove, resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15673 4 Debian, Mozilla, Opensuse and 1 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. 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 < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
CVE-2020-15670 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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 < 80, Firefox ESR < 78.2, Thunderbird < 78.2, and Firefox for Android < 80.
CVE-2020-15669 2 Mozilla, Redhat 5 Firefox Esr, Thunderbird, Enterprise Linux and 2 more 2024-11-21 8.8 High
When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
CVE-2020-15664 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.
CVE-2020-15663 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 8.8 High
If Firefox is installed to a user-writable directory, the Mozilla Maintenance Service would execute updater.exe from the install location with system privileges. Although the Mozilla Maintenance Service does ensure that updater.exe is signed by Mozilla, the version could have been rolled back to a previous version which would have allowed exploitation of an older bug and arbitrary code execution with System Privileges. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, and Firefox ESR < 78.2.

Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. 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 < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.
