|---|---|---|---|---|
| CVE-2020-26966 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-08-04 | 6.5 Medium |
| Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. 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 | 2024-08-04 | 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-2020-26956 | 2 Mozilla, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-08-04 | 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 | 2024-08-04 | 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 | 2024-08-04 | 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 | 2024-08-04 | 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-2020-15646 | 2 Mozilla, Redhat | 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more | 2024-08-04 | 5.9 Medium |
| If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird sends username and password over https to a server controlled by the attacker. This vulnerability affects Thunderbird < 68.10.0. | ||||
| CVE-2020-15673 | 4 Debian, Mozilla, Opensuse and 1 more | 8 Debian Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 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-2020-15655 | 3 Canonical, Mozilla, Opensuse | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-08-04 | 6.5 Medium |
| A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | ||||
| CVE-2020-15685 | 2 Mozilla, Redhat | 3 Thunderbird, Enterprise Linux, Rhel Eus | 2024-08-04 | 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-2020-15678 | 4 Debian, Mozilla, Opensuse and 1 more | 8 Debian Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 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-2020-15669 | 2 Mozilla, Redhat | 5 Firefox Esr, Thunderbird, Enterprise Linux and 2 more | 2024-08-04 | 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-2020-15659 | 4 Canonical, Mozilla, Opensuse and 1 more | 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 8.8 High |
| 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. | ||||
| CVE-2020-15677 | 4 Debian, Mozilla, Opensuse and 1 more | 8 Debian Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 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-2020-15670 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-08-04 | 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-2020-15653 | 3 Canonical, Mozilla, Redhat | 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more | 2024-08-04 | 6.5 Medium |
| An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This could have led to security issues for websites relying on sandbox configurations that allowed popups and hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | ||||
| CVE-2020-15683 | 4 Debian, Mozilla, Opensuse and 1 more | 8 Debian Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 9.8 Critical |
| Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR 78.3.

| CVE-2020-15676 | 4 Debian, Mozilla, Opensuse and 1 more | 8 Debian Linux, Firefox, Firefox Esr and 5 more | 2024-08-04 | 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-2020-15657 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2024-08-04 | 7.8 High |
| Firefox could be made to load attacker-supplied DLL files from the installation directory. This required an attacker that is already capable of placing files in the installation directory. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | ||||
