| CVE-2020-6826 | 1 Mozilla | 1 Firefox | 2024-11-21 | 9.8 Critical |
| Mozilla developers Tyson Smith, Bob Clary, and Alexandru Michis reported memory safety bugs present in Firefox 74. 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 < 75. | ||||
| CVE-2020-6825 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 9.8 Critical |
| Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. 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 Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6824 | 1 Mozilla | 1 Firefox | 2024-11-21 | 2.8 Low |
| Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open. Subsequently, if the user had opened a new Private Browsing Window, revisited the same site, and generated a new password - the generated passwords would have been identical, rather than independent. This vulnerability affects Firefox < 75. | ||||
| CVE-2020-6823 | 1 Mozilla | 1 Firefox | 2024-11-21 | 9.8 Critical |

| On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in <code>GMPDecodeData</code>. It is possible that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6821 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-11-21 | 7.5 High |
| When reading from areas partially or fully outside the source resource with WebGL's <code>copyTexSubImage</code> method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6815 | 1 Mozilla | 1 Firefox | 2024-11-21 | 9.8 Critical |
| Mozilla developers reported memory safety and script safety bugs present in Firefox 73. Some of these bugs showed evidence of memory corruption or escalation of privilege and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 74. | ||||
| CVE-2020-6814 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 9.8 Critical |
| Mozilla developers reported memory safety bugs present in Firefox and Thunderbird 68.5. 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.

| CVE-2020-6812 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 5.3 Medium |
| The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6811 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-11-21 | 8.8 High |
| The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6810 | 1 Mozilla | 1 Firefox | 2024-11-21 | 4.3 Medium |
| After a website had entered fullscreen mode, it could have used a previously opened popup to obscure the notification that indicates the browser is in fullscreen mode. Combined with spoofing the browser chrome, this could have led to confusing the user about the current origin of the page and credential theft or other attacks. This vulnerability affects Firefox < 74. | ||||
| CVE-2020-6809 | 1 Mozilla | 1 Firefox | 2024-11-21 | 7.5 High |
