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-2019-9788 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-2018-5089 4 Canonical, Debian, Mozilla and 1 more 8 Ubuntu Linux, Debian Linux, Firefox and 5 more 2025-11-25 N/A
Memory safety bugs were reported in Firefox 57 and Firefox ESR 52.5. 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 < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2017-5462 2 Debian, Mozilla 4 Debian Linux, Firefox, Network Security Services and 1 more 2025-11-25 N/A
A flaw in DRBG number generation within the Network Security Services (NSS) library where the internal state V does not correctly carry bits over. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 52.1 has been updated with NSS version 3.28.4. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
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-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-2017-5444 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
A buffer overflow vulnerability while parsing "application/http-index-format" format content when the header contains improperly formatted data. This allows for an out-of-bounds read of data from memory. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2019-11693 3 Linux, Mozilla, Redhat 4 Linux Kernel, Firefox, Thunderbird and 1 more 2025-11-25 N/A
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-2018-12371 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 8.8 High
An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 16 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 60.1, Thunderbird < 60, and Firefox < 61.
CVE-2019-9813 2 Mozilla, Redhat 3 Firefox, Thunderbird, Enterprise Linux 2025-11-25 N/A
Incorrect handling of __proto__ mutations may lead to type confusion in IonMonkey JIT code and can be leveraged for arbitrary memory read and write. This vulnerability affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and Thunderbird < 60.6.1.
CVE-2014-1486 7 Canonical, Debian, Fedoraproject and 4 more 17 Ubuntu Linux, Debian Linux, Fedora and 14 more 2025-11-25 9.8 Critical
Use-after-free vulnerability in the imgRequestProxy function in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allows remote attackers to execute arbitrary code via vectors involving unspecified Content-Type values for image data.
CVE-2024-5696 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-06 8.6 High
By manipulating the text in an `&lt;input&gt;` tag, an attacker could have caused corrupt memory leading to a potentially exploitable crash. This vulnerability affects Firefox < 127, Firefox ESR < 115.12, and Thunderbird < 115.12.
CVE-2023-4421 1 Mozilla 1 Nss 2025-11-04 6.5 Medium
The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. This vulnerability affects NSS < 3.61.
CVE-2023-5388 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-04 6.5 Medium
NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data. This vulnerability affects Firefox < 124, Firefox ESR < 115.9, and Thunderbird < 115.9.
CVE-2024-8384 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-04 9.8 Critical
The JavaScript garbage collector could mis-color cross-compartment objects if OOM conditions were detected at the right point between two passes. This could have led to memory corruption. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, Firefox ESR < 115.15, Thunderbird < 128.2, and Thunderbird < 115.15.
CVE-2024-8383 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2025-11-04 7.5 High
Firefox normally asks for confirmation before asking the operating system to find an application to handle a scheme that the browser does not support. It did not ask before doing so for the Usenet-related schemes news: and snews:. Since most operating systems don't have a trusted newsreader installed by default, an unscrupulous program that the user downloaded could register itself as a handler. The website that served the application download could then launch that application at will. This vulnerability affects Firefox < 130, Firefox ESR < 128.2, and Firefox ESR < 115.15.
