| CVE-2020-15669 | Hig | 0.57 | 8.8 | 0.01 | Oct 1, 2020 | 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… | ||
| CVE-2020-15663 | Hig | 0.57 | 8.8 | 0.03 | Oct 1, 2020 | 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… | ||
| CVE-2020-15659 | Hig | 0.57 | 8.8 | 0.02 | Aug 10, 2020 | Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0.

| CVE-2020-12420 | Hig | 0.57 | 8.8 | 0.02 | Jul 9, 2020 | When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. | ||
| CVE-2020-12419 | Hig | 0.57 | 8.8 | 0.02 | Jul 9, 2020 | When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free condition. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10,… | ||
| CVE-2020-12417 | Hig | 0.57 | 8.8 | 0.03 | Jul 9, 2020 | Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier, resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10,… | ||
