CVE-2019-11707 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-31 7.5 HIGH 8.8 HIGH
A type confusion vulnerability can occur when manipulating JavaScript objects due to issues in Array.pop. This can allow for an exploitable crash. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Firefox ESR < 60.7.1, Firefox < 67.0.3, and Thunderbird < 60.7.2.
CVE-2019-11730 4 Debian, Mozilla, Opensuse and 1 more 7 Debian Linux, Firefox, Firefox Esr and 4 more 2023-01-31 4.3 MEDIUM 6.5 MEDIUM
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. It was demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2020-12421 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2023-01-30 4.3 MEDIUM 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 This could have caused add-ons to become out-of-date silently without notification to the user.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-2020-12419 3 Canonical, Mozilla, Opensuse 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2023-01-27 9.3 HIGH 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-2020-12418 3 Canonical, Mozilla, Opensuse 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2023-01-27 4.3 MEDIUM 6.5 MEDIUM
Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12406 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2023-01-27 9.3 HIGH 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-2022-26386 3 Apple, Linux, Mozilla 4 Macos, Linux Kernel, Firefox Esr and 1 more 2023-01-23 N/A 6.5 MEDIUM
Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in <code>/tmp</code>, but this behavior was changed to download them to <code>/tmp</code> where they could be affected by other local users. This behavior was reverted to the original, user-specific directory. <br>*This bug only affects Firefox for macOS and Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 91.7 and Thunderbird < 91.7.
CVE-2013-0796 2 Linux, Mozilla 6 Linux Kernel, Firefox, Firefox Esr and 3 more 2023-01-18 10.0 HIGH N/A
The WebGL subsystem in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, and SeaMonkey before 2.17 on Linux does not properly interact with Mesa drivers, which allows remote attackers to execute arbitrary code or cause a denial of service (free of unallocated memory) via unspecified vectors.
CVE-2022-31740 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-06 N/A 8.8 HIGH
On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation problem, and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-45412 4 Apple, Google, Linux and 1 more 6 Macos, Android, Linux Kernel and 3 more 2023-01-05 N/A 8.8 HIGH
When resolving a symlink such as <code>file:///proc/self/fd/1</code>, an error message may be produced where the symlink was resolved to a string containing unitialized memory in the buffer. <br>*This bug only affects Thunderbird on Unix-based operated systems (Android, Linux, MacOS). Windows is unaffected.*. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-46882 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 9.8 CRITICAL
A use-after-free in WebGL extensions could have led to a potentially exploitable crash. This vulnerability affects Firefox < 107, Firefox ESR < 102.6, and Thunderbird < 102.6.
CVE-2022-45416 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 6.5 MEDIUM
Keyboard events reference strings like "KeyA" that were at fixed, known, and widely-spread addresses. Cache-based timing attacks such as Prime+Probe could have possibly figured out which keys were being pressed. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-45418 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 6.1 MEDIUM
If a custom mouse cursor is specified in CSS, under certain circumstances the cursor could have been drawn over the browser UI, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-45421 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 8.8 HIGH
Mozilla developers Andrew McCreight and Gabriele Svelto reported memory safety bugs present in Thunderbird 102.4. 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 < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-45420 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 6.5 MEDIUM
Use tables inside of an iframe, an attacker could have caused iframe contents to be rendered outside the boundaries of the iframe, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-46874 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 8.8 HIGH
A file with a long filename could have had its filename truncated to remove the valid extension, leaving a malicious extension in its place. This could potentially led to user confusion and the execution of malicious code.<br/>*Note*: This issue was originally included in the advisories for Thunderbird 102.6, but a patch (specific to Thunderbird) was omitted, resulting in it actually being fixed in Thunderbird 102.6.1. This vulnerability affects Firefox < 108, Thunderbird < 102.6.1, Thunderbird < 102.6, and Firefox ESR < 102.6.
CVE-2022-46875 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2023-01-04 N/A 6.5 MEDIUM
The executable file warning was not presented when downloading .atloc and .ftploc files, which can run commands on a user's computer. <br>*Note: This issue only affected Mac OS operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6.
CVE-2022-46878 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 8.8 HIGH
Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.5. 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 < 108, Firefox ESR < 102.6, and Thunderbird < 102.6.
CVE-2022-45410 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 6.5 MEDIUM
When a ServiceWorker intercepted a request with <code>FetchEvent</code>, the origin of the request was lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie protections. This was addressed in the spec and then in browsers. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
CVE-2022-45409 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-01-04 N/A 8.8 HIGH
The garbage collector could have been aborted in several states and zones and <code>GCRuntime::finishCollection</code> may not have been called, leading to a use-after-free and potentially exploitable crash. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
