CVE-2019-11708: sandbox escape using Prompt:Open

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.

Mozilla Foundation reports:

Jann Horn of Google Project Zero Security reported that speculative execution performed by modern CPUs could leak information through a timing side-channel attack. Microsoft Vulnerability Research extended this attack to browser JavaScript engines and demonstrated that code on a malicious web page could read data from other web sites (violating the same-origin policy) or private data from the browser itself.

Since this new class of attacks involves measuring precise time intervals, as a parti al, short-term, mitigation we are disabling or reducing the precision of several time sources in Firefox. The precision of performance.now() has been reduced from 5μs to 20μs, and the SharedArrayBuffer feature has been disabled because it can be used to construct a high-resolution timer.

CVE-2018-12386: Type confusion in JavaScript

A vulnerability in register allocation in JavaScript can lead to type confusion, allowing for an arbitrary read and write. This leads to remote code execution inside the sandboxed content process when triggered.

CVE-2018-12387:

A vulnerability where the JavaScript JIT compiler inlines Array.prototype.push with multiple arguments that results in the stack pointer being off by 8 bytes after a bailout. This leaks a memory address to the calling function which can be used as part of an exploit inside the sandboxed content process.
