| CVE-2021-38505 | 2 Microsoft, Mozilla | 4 Windows 10, Firefox, Firefox Esr and 1 more | 2021-12-10 | 6.5 Medium |
| Microsoft introduced a new feature in Windows 10 known as Cloud Clipboard which, if enabled, will record data copied to the clipboard to the cloud, and make it available on other computers in certain scenarios. Applications that wish to prevent copied data from being recorded in Cloud History must use specific clipboard formats; and Firefox before versions 94 and ESR 91.3 did not implement them. This could have caused sensitive data to be recorded to a user's Microsoft account. *This bug only affects Firefox for Windows 10+ with Cloud Clipboard enabled. Other operating systems are unaffected.*. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3. | ||||
| CVE-2021-38497 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-11-04 | 6.5 Medium |
| Through use of reportValidity() and window.open(), a plain-text validation message could have been overlaid on another origin, leading to possible user confusion and spoofing attacks. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | ||||
| CVE-2021-38498 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-11-04 | 7.5 High |
| During process shutdown, a document could have caused a use-after-free of a languages service object, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | ||||
| CVE-2021-38501 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-11-04 | 8.8 High |
| Mozilla developers reported memory safety bugs present in Firefox 92 and Firefox ESR 91.1. 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 < 93, Thunderbird < 91.2, and Firefox ESR < 91.2. | ||||
| CVE-2020-6797 | 2 Apple, Mozilla | 4 Macos, Firefox, Firefox Esr and 1 more | 2021-09-16 | 4.3 Medium |
| By downloading a file with the .fileloc extension, a semi-privileged extension could launch an arbitrary application on the user's computer. The attacker is restricted as they are unable to download non-quarantined files or supply command line arguments to the application, limiting the impact. Note: this issue only occurs on Mac OSX. Other operating systems are unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5. | ||||
| CVE-2019-9815 | 2 Apple, Mozilla | 4 Macos, Firefox, Firefox Esr and 1 more | 2021-09-08 | N/A |
| If hyperthreading is not disabled, a timing attack vulnerability exists, similar to previous Spectre attacks. Apple has shipped macOS 10.14.5 with an option to disable hyperthreading in applications running untrusted code in a thread through a new sysctl. Firefox now makes use of it on the main thread and any worker threads. *Note: users need to update to macOS 10.14.5 in order to take advantage of this change.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. | ||||
| CVE-2021-23982 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-08-06 | 6.5 Medium |
| Using techniques that built on the slipstream research, a malicious webpage could have scanned both an internal network's hosts as well as services running on the user's local machine utilizing WebRTC connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2021-23984 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-08-06 | 6.5 Medium |
| A malicious extension could have opened a popup window lacking an address bar. The title of the popup lacking an address bar should not be fully controllable, but in this situation was. This could have been used to spoof a website and attempt to trick the user into providing credentials. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. | ||||
| CVE-2019-9794 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | N/A |
| 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-2019-9800 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | N/A |
| Mozilla developers and community members reported memory safety bugs present in Firefox 66, Firefox ESR 60.6, and Thunderbird 60.6. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. | ||||
| CVE-2020-6825 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 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-2019-11693 | 2 Linux, Mozilla | 4 Linux Kernel, Firefox, Firefox Esr and 1 more | 2021-07-21 | N/A |
| 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-2020-6821 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 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-2020-6828 | 2 Google, Mozilla | 2 Android, Firefox Esr | 2021-07-21 | 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-2020-12393 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 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-2019-9812 | 1 Mozilla | 2 Firefox, Firefox Esr | 2021-07-21 | 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-2020-6831 | 4 Canonical, Debian, Mozilla and 1 more | 6 Ubuntu Linux, Debian Linux, Firefox and 3 more | 2021-07-21 | 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. | ||||
| CVE-2020-15670 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 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-2019-9819 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | N/A |
| A vulnerability where a JavaScript compartment mismatch can occur while working with the fetch API, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. | ||||
| CVE-2019-9818 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 8.3 High |
| A race condition is present in the crash generation server used to generate data for the crash reporter. This issue can lead to a use-after-free in the main process, resulting in a potentially exploitable crash and a sandbox escape. *Note: this vulnerability only affects Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7. | ||||
