This update bumps the package to the latest stable version containing a
few security fixes:
- 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.
