            | CVE | Vendors | Products | Updated | CVSS v3.1 | 
|---|---|---|---|---|
| CVE-2025-9185 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2025-10-30 | 8.1 High | 
| Memory safety bugs present in Firefox ESR 115.26, Firefox ESR 128.13, Thunderbird ESR 128.13, Firefox ESR 140.1, Thunderbird ESR 140.1, Firefox 141 and Thunderbird 141. 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 < 142, Firefox ESR < 115.27, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | ||||

| Uninitialized memory in the JavaScript Engine component. This vulnerability affects Firefox < 142, Firefox ESR < 128.14, Firefox ESR < 140.2, Thunderbird < 142, Thunderbird < 128.14, and Thunderbird < 140.2. | ||||
| CVE-2025-9179 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2025-10-30 | 9.8 Critical | 
| An attacker was able to perform memory corruption in the GMP process which processes encrypted media. This process is also heavily sandboxed, but represents slightly different privileges from the content process.

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-2019-11708 | 2 Mozilla, Redhat | 3 Firefox, Thunderbird, Enterprise Linux | 2025-10-27 | 10.0 Critical | 
| Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2. | ||||
| CVE-2023-4863 | 10 Bandisoft, Bentley, Debian and 7 more | 17 Honeyview, Seequent Leapfrog, Debian Linux and 14 more | 2025-10-24 | 8.8 High |

| CVE-2023-5217 | 8 Apple, Debian, Fedoraproject and 5 more | 15 Ipados, Iphone Os, Debian Linux and 12 more | 2025-10-24 | 8.8 High | 
| Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2013-1690 | 6 Canonical, Debian, Mozilla and 3 more | 17 Ubuntu Linux, Debian Linux, Firefox and 14 more | 2025-10-22 | 8.8 High | 
| Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 do not properly handle onreadystatechange events in conjunction with page reloading, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted web site that triggers an attempt to execute data at an unmapped memory location. | ||||
| CVE-2013-1675 | 5 Canonical, Debian, Mozilla and 2 more | 20 Ubuntu Linux, Debian Linux, Firefox and 17 more | 2025-10-22 | 6.5 Medium | 
| Mozilla Firefox before 21.0, Firefox ESR 17.x before 17.0.6, Thunderbird before 17.0.6, and Thunderbird ESR 17.x before 17.0.6 do not properly initialize data structures for the nsDOMSVGZoomEvent::mPreviousScale and nsDOMSVGZoomEvent::mNewScale functions, which allows remote attackers to obtain sensitive information from process memory via a crafted web site. | ||||
| CVE-2010-3765 | 2 Mozilla, Redhat | 4 Firefox, Seamonkey, Thunderbird and 1 more | 2025-10-22 | 9.8 Critical | 
| Mozilla Firefox 3.5.x through 3.5.14 and 3.6.x through 3.6.11, Thunderbird 3.1.6 before 3.1.6 and 3.0.x before 3.0.10, and SeaMonkey 2.x before 2.0.10, when JavaScript is enabled, allows remote attackers to execute arbitrary code via vectors related to nsCSSFrameConstructor::ContentAppended, the appendChild method, incorrect index tracking, and the creation of multiple frames, which triggers memory corruption, as exploited in the wild in October 2010 by the Belmoo malware. | ||||
