CVE-2018-5174 2 Microsoft, Mozilla 5 Windows 10, Firefox, Firefox Esr and 2 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
In the Windows 10 April 2018 Update, Windows Defender SmartScreen honors the "SEE_MASK_FLAG_NO_UI" flag associated with downloaded files and will not show any UI. Files that are unknown and potentially dangerous will be allowed to run because SmartScreen will not prompt the user for a decision, and if the user is offline all files will be allowed to be opened because Windows won't prompt the user to ask what to do. Firefox incorrectly sets this flag when downloading files, leading to less secure behavior from SmartScreen. Note: this issue only affects Windows 10 users running the April 2018 update or later. It does not affect other Windows users or other operating systems. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2019-11708 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-08-15 10.0 HIGH 10.0 CRITICAL
Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
CVE-2019-11712 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-29 6.8 MEDIUM 8.8 HIGH
POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2019-11713 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-29 7.5 HIGH 9.8 CRITICAL

CVE-2019-11698 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-28 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-2019-11691 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-26 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur when working with XMLHttpRequest (XHR) in an event loop, causing the XHR main thread to be called after it has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2019-9817 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-26 5.0 MEDIUM 5.3 MEDIUM
Images from a different domain can be read using a canvas object in some circumstances. This could be used to steal image data from a different site in violation of same-origin policy. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2019-9820 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-26 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur in the chrome event handler when it is freed while still in use. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2019-11692 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-07-25 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur when listeners are removed from the event listener manager while still in use, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
CVE-2019-9796 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-06-26 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-2019-9790 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-05-13 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2019-9793 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2019-05-13 4.3 MEDIUM 5.9 MEDIUM
A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. *Note: Spectre mitigations are currently enabled for all users by default settings.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2019-9801 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2019-04-29 5.0 MEDIUM 5.3 MEDIUM
Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66.
CVE-2015-0831 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2019-04-22 6.8 MEDIUM N/A
