Mozilla Firefox < 66.0.1

High Nessus Plugin ID 123011

Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 66.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-09 advisory.

- 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.
(CVE-2019-9813)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Mozilla Firefox version 66.0.1 or later.
