CVE-2020-15675 1 Mozilla 1 Firefox 2021-07-21 6.8 MEDIUM 8.8 HIGH
When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 81.
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-2020-15684 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers reported memory safety bugs present in Firefox 81. 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 < 82.
CVE-2020-6815 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 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-2019-9814 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 66. 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 Firefox < 67.
CVE-2020-6826 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 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-2019-11734 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 68. 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 Firefox < 69.
CVE-2020-15674 1 Mozilla 1 Firefox 2021-07-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 80. 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 < 81.
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-2019-11693 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-2019-17019 2 Microsoft, Mozilla 2 Windows, Firefox 2021-07-21 6.8 MEDIUM 8.8 HIGH
When Python was installed on Windows, a python file being served with the MIME type of text/plain could be executed by Python instead of being opened as a text file when the Open option was selected upon download. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 72.
CVE-2020-15651 2 Apple, Mozilla 2 Iphone Os, Firefox 2021-07-21 4.3 MEDIUM 4.3 MEDIUM
A unicode RTL order character in the downloaded file name can be used to change the file's name during the download UI flow to change the file extension. This vulnerability affects Firefox for iOS < 28.
CVE-2019-9789 1 Mozilla 1 Firefox 2021-07-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 65. 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 Firefox < 66.
CVE-2020-15671 1 Mozilla 1 Firefox 2021-07-21 2.6 LOW 3.1 LOW
When typing in a password under certain conditions, a race may have occured where the InputContext was not being correctly set for the input field, resulting in the typed password being saved to the keyboard dictionary. This vulnerability affects Firefox for Android < 80.
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. 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-2019-9802 1 Mozilla 1 Firefox 2021-07-21 5.0 MEDIUM 7.5 HIGH
If a Sandbox content process is compromised, it can initiate an FTP download which will then use a child process to render the downloaded data. The downloaded data can then be passed to the Chrome process with an arbitrary file length supplied by an attacker, bypassing sandbox protections and allow for a potential memory read of adjacent data from the privileged Chrome process, which may include sensitive data. This vulnerability affects Firefox < 66.
CVE-2020-6809 1 Mozilla 1 Firefox 2021-07-21 5.0 MEDIUM 7.5 HIGH
When a Web Extension had the all-urls permission and made a fetch request with a mode set to 'same-origin', it was possible for the Web Extension to read local files. This vulnerability affects Firefox < 74.
CVE-2020-12411 1 Mozilla 1 Firefox 2021-07-21 9.3 HIGH 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 76. 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 < 77.
CVE-2020-12404 1 Mozilla 1 Firefox 2021-07-21 4.3 MEDIUM 4.3 MEDIUM
For native-to-JS bridging the app requires a unique token to be passed that ensures non-app code can't call the bridging functions. That token could leak when used for downloading files. This vulnerability affects Firefox for iOS < 26.
CVE-2020-12407 1 Mozilla 1 Firefox 2021-07-21 2.6 LOW 6.5 MEDIUM
Mozilla Developer Nicolas Silva found that when using WebRender, Firefox would under certain conditions leak arbitrary GPU memory to the visible screen. The leaked memory content was visible to the user, but not observable from web content. This vulnerability affects Firefox < 77.
