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.
| Vendor | Product | Versions |

Mozilla | Thunderbird | affected unspecified - < 60.7 |
Mozilla | Firefox | affected unspecified - < 67 |
Mozilla | Firefox ESR | affected unspecified - < 60.7 |
