CVE-2014-1547 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-25 10.0 HIGH N/A
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
CVE-2017-5455 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Enterprise Linux Desktop and 4 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
The internal feed reader APIs that crossed the sandbox barrier allowed for a sandbox escape and escalation of privilege if combined with another vulnerability that resulted in remote code execution inside the sandboxed process. This vulnerability affects Firefox ESR < 52.1 and Firefox < 53.
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-2018-12386 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 5.8 MEDIUM 8.1 HIGH
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-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
Use-after-free vulnerability in the nsHostResolver::ConditionallyRefreshRecord function in libxul.so in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors related to host resolution.
CVE-2018-5159 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
An integer overflow can occur in the Skia library due to 32-bit integer use in an array without integer overflow checks, resulting in possible out-of-bounds writes. This could lead to a potentially exploitable crash triggerable by web content. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2019-9788 2 Mozilla, Redhat 6 Firefox, Thunderbird, Enterprise Linux and 3 more 2025-11-25 7.5 HIGH 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-2017-5378 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
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-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-2017-5396 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 the Media Decoder when working with media files when some events are fired after the media elements are freed from memory. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
CVE-2017-5446 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
An out-of-bounds read when an HTTP/2 connection to a servers sends "DATA" frames with incorrect data content. This leads to a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2019-9812 1 Mozilla 1 Firefox 2025-11-25 5.8 MEDIUM 9.3 CRITICAL
Given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered. This vulnerability affects Firefox ESR < 60.9, Firefox ESR < 68.1, and Firefox < 69.
CVE-2018-5099 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 when the widget listener is holding strong references to browser objects that have previously been freed, resulting in a potentially exploitable crash when these references are used. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2018-5146 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
An out of bounds memory write while processing Vorbis audio data was reported through the Pwn2Own contest. This vulnerability affects Firefox < 59.0.1, Firefox ESR < 52.7.2, and Thunderbird < 52.7.
CVE-2013-5595 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 4.3 MEDIUM N/A
The JavaScript engine 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 allocate memory for unspecified functions, which allows remote attackers to conduct buffer overflow attacks via a crafted web page.
CVE-2017-5445 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
A vulnerability while parsing "application/http-index-format" format content where uninitialized values are used to create an array. This could allow the reading of uninitialized memory into the arrays affected. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2019-11694 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 5.0 MEDIUM 7.5 HIGH
A vulnerability exists in the Windows sandbox where an uninitialized value in memory can be leaked to a renderer from a broker when making a call to access an otherwise unavailable file. This results in the potential leaking of information stored at that memory location. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2013-5600 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 10.0 HIGH N/A
Use-after-free vulnerability in the nsIOService::NewChannelFromURIWithProxyFlags function 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 via vectors involving a blob: URL.
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.
