Mozilla Firefox < 62.0.3 Multiple Vulnerabilities

Versions of Mozilla Firefox prior to 62.0.3 are unpatched for the following vulnerabilities as referenced in the mfsa2018-24 advisory:

• 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-2018-12386)
• 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. (CVE-2018-12387)
