CVE-2019-9788 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 9.8 Critical
Mozilla developers and community members reported memory safety bugs present in Firefox 65, Firefox ESR 60.5, and Thunderbird 60.5. 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 < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2019-9791 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 9.8 Critical
The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2019-9792 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 9.8 Critical
The IonMonkey just-in-time (JIT) compiler can leak an internal JS_OPTIMIZED_OUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2018-18493 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 N/A
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2019-11711 3 Debian, Mozilla, Redhat 4 Debian Linux, Firefox, Thunderbird and 1 more 2025-11-25 8.8 High
When an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain to relax their origin security. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2019-11717 5 Debian, Mozilla, Novell and 2 more 6 Debian Linux, Firefox, Thunderbird and 3 more 2025-11-25 5.3 Medium
A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2018-12390 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 N/A
Mozilla developers and community members reported memory safety bugs present in Firefox 62 and Firefox ESR 60.2. 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 < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
CVE-2018-12386 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 N/A
A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered. This vulnerability affects Firefox ESR < 60.2.2 and Firefox < 62.0.3.
CVE-2018-5095 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 N/A
An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2019-11740 4 Canonical, Mozilla, Opensuse and 1 more 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more 2025-11-25 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 68, Firefox ESR 68, and Firefox 60.8. 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, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.
CVE-2018-12377 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 N/A
A use-after-free vulnerability can occur when refresh driver timers are refreshed in some circumstances during shutdown when the timer is deleted while still in use. This results in a potentially exploitable crash. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.
CVE-2017-7751 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
A use-after-free vulnerability with content viewer listeners that results in a potentially exploitable crash. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2018-12378 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 N/A
A use-after-free vulnerability can occur when an IndexedDB index is deleted while still in use by JavaScript code that is providing payload values to be stored. This results in a potentially exploitable crash. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.
CVE-2017-5396 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A

CVE-2018-12379 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Thunderbird and 7 more 2025-11-25 N/A
When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of-bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.
CVE-2019-11753 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2025-11-25 7.8 High
The Firefox installer allows Firefox to be installed to a custom user writable location, leaving it unprotected from manipulation by unprivileged users or malware. If the Mozilla Maintenance Service is manipulated to update this unprotected location and the updated maintenance service in the unprotected location has been altered, the altered maintenance service can run with elevated privileges during the update process due to a lack of integrity checks. This allows for privilege escalation if the executable has been replaced locally. <br>*Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Firefox < 69, Firefox ESR < 60.9, and Firefox ESR < 68.1.
CVE-2016-9895 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A

A use-after-free can occur when events are fired for a "FontFace" object after the object has been already been destroyed while working with fonts. This results in a potentially exploitable crash. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.
CVE-2017-5447 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
