| CVE-2019-9794 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. | |||||
| CVE-2019-9812 | 1 Mozilla | 2 Firefox, Firefox Esr | 2021-07-21 | 5.8 MEDIUM | 9.3 CRITICAL |
| Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered. This vulnerability affects Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69. | |||||
| CVE-2019-9800 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| Mozilla developers and community members reported memory safety bugs present in Firefox 66, Firefox ESR 60.6, and Thunderbird 60.6.

| CVE-2019-11693 | 2 Linux, Mozilla | 4 Linux Kernel, Firefox, Firefox Esr and 1 more | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| The bufferdata function in WebGL is vulnerable to a buffer overflow with specific graphics drivers on Linux. This could result in malicious content freezing a tab or triggering a potentially exploitable crash. *Note: this issue only occurs on Linux. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. | |||||
| CVE-2020-12393 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 4.6 MEDIUM | 7.8 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. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | |||||
| CVE-2020-15670 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 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-2020-6828 | 2 Google, Mozilla | 2 Android, Firefox Esr | 2021-07-21 | 6.4 MEDIUM | 7.5 HIGH |
| A malicious Android application could craft an Intent that would have been processed by Firefox for Android and potentially result in a file overwrite in the user's profile directory. One exploitation vector for this would be to supply a user.js file providing arbitrary malicious preference values. Control of arbitrary preferences can lead to sufficient compromise such that it is generally equivalent to arbitrary code execution.<br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.7. | |||||
| CVE-2020-6821 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 5.0 MEDIUM | 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-2020-6831 | 4 Canonical, Debian, Mozilla and 1 more | 6 Ubuntu Linux, Debian Linux, Firefox and 3 more | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | |||||
