CVE-2017-7764 3 Debian, Mozilla, Redhat 4 Debian Linux, Firefox, Thunderbird and 1 more 2025-11-25 N/A
Characters from the "Canadian Syllabics" unicode block can be mixed with characters from other unicode blocks in the addressbar instead of being rendered as their raw "punycode" form, allowing for domain name spoofing attacks through character confusion. The current Unicode standard allows characters from "Aspirational Use Scripts" such as Canadian Syllabics to be mixed with Latin characters in the "moderately restrictive" IDN profile. We have changed Firefox behavior to match the upcoming Unicode version 10.0 which removes this category and treats them as "Limited Use Scripts.". This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2019-11709 5 Debian, Mozilla, Opensuse and 2 more 7 Debian Linux, Firefox, Thunderbird and 4 more 2025-11-25 9.8 Critical
Mozilla developers and community members reported memory safety bugs present in Firefox 67 and Firefox ESR 60.7. 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 Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.

This results in a potentially exploitable crash. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-7749 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A

CVE-2017-5470 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
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-2017-5469 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A

CVE-2017-5466 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
If a page is loaded from an original site through a hyperlink and contains a redirect to a "data:text/html" URL, triggering a reload will run the reloaded "data:text/html" page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-7791 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
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-2017-5465 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
An out-of-bounds read while processing SVG content in "ConvolvePixel". This results in a crash and also allows for otherwise inaccessible memory being copied into SVG graphic content, which could then displayed. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-5460 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
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-2017-5454 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
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-2017-5451 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A
A mechanism to spoof the addressbar through the user interaction on the addressbar and the "onblur" event. The event could be used by script to affect text display to make the loaded site appear to be different from the one actually loaded within the addressbar. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-5449 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2025-11-25 N/A

CVE-2017-7765 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2025-11-25 N/A
The "Mark of the Web" was not correctly saved on Windows when files with very long names were downloaded from the Internet. Without the Mark of the Web data, the security warning that Windows displays before running executables downloaded from the Internet is not shown. 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-2018-5187 3 Canonical, Debian, Mozilla 4 Ubuntu Linux, Debian Linux, Firefox and 1 more 2025-11-25 N/A
Memory safety bugs present in Firefox 60 and Firefox ESR 60. 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, Firefox ESR < 60.1, and Firefox < 61.
CVE-2017-5447 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
