  - Incorrect alias information in IonMonkey JIT compiler
    for Array.prototype.slice method may lead to missing
    bounds check and a buffer overflow. (CVE-2019-9810)

  - Incorrect handling of __proto__ mutations may lead to
    type confusion in IonMonkey JIT code and can be
    leveraged for arbitrary memory read and write.

only on the application's self-reported version number.");
