CVE-2019-9815

Priority
Description
If hyperthreading is not disabled, a timing attack vulnerability exists,
similar to previous Spectre attacks. Apple has shipped macOS 10.14.5 with
an option to disable hyperthreading in applications running untrusted code
in a thread through a new sysctl. Firefox now makes use of it on the main
thread and any worker threads. *Note: users need to update to macOS 10.14.5
in order to take advantage of this change.*. This vulnerability affects
Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
