Memory corruption
The IonMonkey just-in-time JIT compiler can leak an internal JSOPTIMIZEDOUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash. This vulnerability affects Thunderbird...
Type confusion
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...
CVE-2019-9795
A vulnerability where type-confusion in the IonMonkey just-in-time JIT compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash. This vulnerability affects Thunderbird 60.6, Firefox ESR 60.6, and Firefox 66...
CVE-2019-9791
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...
CVE-2019-9796
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 leav...
CVE-2019-9793
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...

CVE-2019-9793
CVE-2019-9793 describes an issue where, if Spectre mitigations are disabled, bounds checking is loosened for string/array/typed array accesses, enabling an attacker to cause the range analysis to infer controlled, incorrect values in JavaScript. Connected advisories confirm affected products and ...
CVE-2019-9801
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...
CVE-2019-9791
CVE-2019-9791 affects Thunderbird and Firefox (including Firefox ESR) and stems from the IonMonkey JIT: type confusion for constructors entered via on-stack replacement. The advisory notes that the vulnerability can enable arbitrary reading/writing of objects during an exploitable crash, with fix...
CVE-2019-9801
CVE-2019-9801 affects Mozilla Firefox and Thunderbird on Windows. The issue allows Firefox/Thunderbird to treat any registered Program ID as an external protocol handler and offer to launch a local application when a matching URL is opened, even if the program is not intended as a URL handler. Ro...

CVE-2019-9790
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-2019-9794
A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the...
