CVE-2017-7779 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Firefox 54, Firefox ESR 52.2, and Thunderbird 52.2. 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 < 52.3, Firefox ESR < 52.3, and Firefox < 55.

The ConvolveHorizontally function in Skia, as used in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, does not properly handle the discarding of image data during function execution, which allows remote attackers to execute arbitrary code by triggering prolonged image scaling, as demonstrated by scaling of a high-quality image.
CVE-2016-10196 3 Debian, Libevent Project, Mozilla 4 Debian Linux, Libevent, Firefox and 1 more 2025-11-25 5.0 MEDIUM 7.5 HIGH
Stack-based buffer overflow in the evutil_parse_sockaddr_port function in evutil.c in libevent before 2.1.6-beta allows attackers to cause a denial of service (segmentation fault) via vectors involving a long string in brackets in the ip_as_string argument.
CVE-2017-5404 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 error can occur when manipulating ranges in selections with one node inside a native anonymous tree and one node outside of it. This results in a potentially exploitable crash. This vulnerability affects Firefox < 52, Firefox ESR < 45.8, Thunderbird < 52, and Thunderbird < 45.8.
CVE-2018-5144 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2025-11-25 7.5 HIGH 7.3 HIGH

CVE-2014-1486 7 Canonical, Debian, Fedoraproject and 4 more 16 Ubuntu Linux, Debian Linux, Fedora and 13 more 2025-11-25 10.0 HIGH 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-2014-1508 6 Canonical, Debian, Mozilla and 3 more 16 Ubuntu Linux, Debian Linux, Firefox and 13 more 2025-11-25 6.4 MEDIUM 9.1 CRITICAL
The libxul.so!gfxContext::Polygon function in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allows remote attackers to obtain sensitive information from process memory, cause a denial of service (out-of-bounds read and application crash), or possibly bypass the Same Origin Policy via vectors involving MathML polygon rendering.
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-2017-5459 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-25 7.5 HIGH 9.8 CRITICAL
A buffer overflow in WebGL triggerable by web content, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.

This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2018-12405 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
Mozilla developers and community members reported memory safety bugs present in Firefox 63 and Firefox ESR 60.3. 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 < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2018-5096 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 can occur while editing events in form elements on a page, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 52.6 and Thunderbird < 52.6.
CVE-2018-12397 4 Canonical, Debian, Mozilla and 1 more 7 Ubuntu Linux, Debian Linux, Firefox and 4 more 2025-11-25 3.6 LOW 7.1 HIGH
A WebExtension can request access to local files without the warning prompt stating that the extension will "Access your data for all websites" being displayed to the user. This allows extensions to run content scripts in local pages without permission warnings when a local file is opened. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-12379 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 4.6 MEDIUM 7.8 HIGH
When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of-bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1.
