CVE-2020-15656 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-08-04 8.8 High
JIT optimizations involving the Javascript arguments object could confuse later optimizations. This risk was already mitigated by various precautions in the code, resulting in this bug rated at only moderate severity. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15654 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 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-2020-15658 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 6.5 Medium
The code for downloading files did not properly take care of special characters, which led to an attacker being able to cut off the file ending at an earlier position, leading to a different file type being downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-12397 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Thunderbird, Enterprise Linux and 2 more 2024-08-04 4.3 Medium
By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0.
CVE-2020-12398 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Thunderbird, Enterprise Linux and 2 more 2024-08-04 7.5 High
If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection. This vulnerability affects Thunderbird < 68.9.0.
CVE-2020-12421 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 6.5 Medium
When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12395 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 9.8 Critical
Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR 68.7. 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 ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12392 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 5.5 Medium
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data 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 the disclosure of local files. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-12417 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-08-04 8.8 High
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, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12406 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 8.8 High
Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2020-12419 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-08-04 8.8 High
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, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12405 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-08-04 5.3 Medium
When browsing a malicious page, a race condition in our SharedWorkerService could occur and lead to a potentially exploitable crash. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2020-12420 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-08-04 8.8 High
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-2020-12393 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-08-04 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-2020-12399 3 Debian, Mozilla, Redhat 5 Debian Linux, Firefox, Firefox Esr and 2 more 2024-08-04 4.4 Medium

CVE-2020-6811 3 Canonical, Mozilla, Redhat 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more 2024-08-04 8.8 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. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2020-6819 2 Mozilla, Redhat 5 Firefox, Firefox Esr, Thunderbird and 2 more 2024-08-04 8.1 High
Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1.
CVE-2020-6794 3 Canonical, Mozilla, Redhat 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more 2024-08-04 6.5 Medium
If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5.
