On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2014-1538 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-25 10.0 HIGH N/A
Use-after-free vulnerability in the nsTextEditRules::CreateMozBR function 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 unspecified vectors.
CVE-2019-11698 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 5.0 MEDIUM 5.3 MEDIUM
If a crafted hyperlink is dragged and dropped to the bookmark bar or sidebar and the resulting bookmark is subsequently dragged and dropped into the web content area, an arbitrary query of a user's browser history can be run and transmitted to the content page via drop event data. This allows for the theft of browser history by a malicious site. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2018-5158 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
The PDF viewer does not sufficiently sanitize PostScript calculator functions, allowing malicious JavaScript to be injected through a crafted PDF file. This JavaScript can then be run with the permissions of the PDF viewer by its worker. This vulnerability affects Firefox ESR < 52.8 and Firefox < 60.
CVE-2014-1481 7 Canonical, Debian, Fedoraproject and 4 more 17 Ubuntu Linux, Debian Linux, Fedora and 14 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 allow remote attackers to bypass intended restrictions on window objects by leveraging inconsistency in native getter methods across different JavaScript engines.
CVE-2018-5125 4 Canonical, Debian, Mozilla and 1 more 7 Ubuntu Linux, Debian Linux, Firefox and 4 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
Memory safety bugs were reported in Firefox 58 and Firefox ESR 52.6. 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 < 52.7, Firefox ESR < 52.7, and Firefox < 59.
CVE-2013-5599 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 10.0 HIGH N/A
Use-after-free vulnerability in the nsIPresShell::GetPresContext function in the PresShell (aka presentation shell) implementation in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) via vectors involving a CANVAS element, a mozTextStyle attribute, and an onresize event.
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-2018-12377 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
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-2017-5454 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
A mechanism to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-7755 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 6.8 MEDIUM 7.8 HIGH
The Firefox installer on Windows can be made to load malicious DLL files stored in the same directory as the installer when it is run. This allows privileged execution if the installer is run with elevated privileges. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2019-9796 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2016-5291 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2025-11-25 4.9 MEDIUM 5.5 MEDIUM
A same-origin policy bypass with local shortcut files to load arbitrary local content from disk. This vulnerability affects Thunderbird < 45.5, Firefox ESR < 45.5, and Firefox < 50.
CVE-2014-1532 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

CVE-2017-5470 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 Firefox 53 and Firefox ESR 52.1. 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 < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2013-5604 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 9.3 HIGH N/A
The txXPathNodeUtils::getBaseURI function in the XSLT processor in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 does not properly initialize data, which allows remote attackers to execute arbitrary code or cause a denial of service (stack-based buffer overflow and application crash) via crafted documents.
CVE-2018-5155 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
A use-after-free vulnerability can occur while adjusting layout during SVG animations with text paths. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2014-1567 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-25 9.3 HIGH N/A
Use-after-free vulnerability in DirectionalityUtils.cpp in Mozilla Firefox before 32.0, Firefox ESR 24.x before 24.8 and 31.x before 31.1, and Thunderbird 24.x before 24.8 and 31.x before 31.1 allows remote attackers to execute arbitrary code via text that is improperly handled during the interaction between directionality resolution and layout.
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-2014-1491 7 Canonical, Debian, Fedoraproject and 4 more 13 Ubuntu Linux, Debian Linux, Fedora and 10 more 2025-11-25 4.3 MEDIUM N/A
Mozilla Network Security Services (NSS) before 3.15.4, as used in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, SeaMonkey before 2.24, and other products, does not properly restrict public values in Diffie-Hellman key exchanges, which makes it easier for remote attackers to bypass cryptographic protection mechanisms in ticket handling by leveraging use of a certain value.
