CVE-2016-9066 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2025-11-25 5.0 MEDIUM 7.5 HIGH
A buffer overflow resulting in a potentially exploitable crash due to memory allocation issues when handling large amounts of incoming data. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2014-1514 6 Canonical, Debian, Mozilla and 3 more 16 Ubuntu Linux, Debian Linux, Firefox and 13 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
vmtypedarrayobject.cpp in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 does not validate the length of the destination array before a copy operation, which allows remote attackers to execute arbitrary code or cause a denial of service (out-of-bounds write and application crash) by triggering incorrect use of the TypedArrayObject class.
CVE-2017-7823 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-25 4.3 MEDIUM 5.4 MEDIUM
The content security policy (CSP) "sandbox" directive did not create a unique origin for the document, causing it to behave as if the "allow-same-origin" keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2013-5593 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 4.3 MEDIUM N/A
The SELECT element implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly restrict the nature or placement of HTML within a dropdown menu, which allows remote attackers to spoof the address bar or conduct clickjacking attacks via vectors that trigger navigation off of a page containing this element.
CVE-2019-11719 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 5.0 MEDIUM 7.5 HIGH
When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2014-1524 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
The nsXBLProtoImpl::InstallImplementation function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 does not properly check whether objects are XBL objects, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted JavaScript code that accesses a non-XBL object as if it were an XBL object.
CVE-2013-5613 6 Canonical, Fedoraproject, Mozilla and 3 more 16 Ubuntu Linux, Fedora, Firefox and 13 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
Use-after-free vulnerability in the PresShell::DispatchSynthMouseMove function in Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving synthetic mouse movement, related to the RestyleManager::GetHoverGeneration function.
CVE-2016-9893 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Thunderbird 45.5. 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 Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.
CVE-2016-9905 3 Debian, Mozilla, Redhat 6 Debian Linux, Firefox, Thunderbird and 3 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
A potentially exploitable crash in "EnumerateSubDocuments" while adding or removing sub-documents. This vulnerability affects Firefox ESR < 45.6 and Thunderbird < 45.6.
CVE-2017-5436 4 Debian, Mozilla, Redhat and 1 more 10 Debian Linux, Firefox, Thunderbird and 7 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. This results in a potentially exploitable crash. This issue was fixed in the Graphite 2 library as well as Mozilla products. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2016-5294 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 2.1 LOW 5.5 MEDIUM
The Mozilla Updater can be made to choose an arbitrary target working directory for output files resulting from the update process. This vulnerability requires local system access. Note: this issue only affects Windows operating systems. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2019-9791 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 7.5 HIGH 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-2013-6671 6 Canonical, Fedoraproject, Mozilla and 3 more 16 Ubuntu Linux, Fedora, Firefox and 13 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
The nsGfxScrollFrameInner::IsLTR function in Mozilla Firefox before 26.0, Firefox ESR 24.x before 24.2, Thunderbird before 24.2, and SeaMonkey before 2.23 allows remote attackers to execute arbitrary code via crafted use of JavaScript code for ordered list elements.
CVE-2014-1541 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-25 10.0 HIGH N/A
Use-after-free vulnerability in the RefreshDriverTimer::TickDriver function in the SMIL Animation Controller in Mozilla Firefox before 30.0, Firefox ESR 24.x before 24.6, and Thunderbird before 24.6 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted web content.

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-2017-5460 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability in frame selection triggered by a combination of malicious script content and key presses by a user. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2018-5150 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Firefox 59, Firefox ESR 52.7, and Thunderbird 52.7. 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 < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2017-5405 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 5.0 MEDIUM 5.3 MEDIUM

CVE-2018-5103 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur during mouse event handling due to issues with multiprocess support. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2018-5129 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 5.0 MEDIUM 8.6 HIGH
A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages.
