| CVE-2020-15670 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 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 | 1 Mozilla | 2 Firefox Esr, Thunderbird | 2024-11-21 | 6.8 MEDIUM | 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 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2024-11-21 | 4.3 MEDIUM | 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 | 9.3 HIGH | 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. | |||||

| CVE-2020-15654 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. | |||||
| CVE-2020-15653 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 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-2020-15652 | 2 Canonical, Mozilla | 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
