Synopsis

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

Description

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.0.1. It is, therefore, affected by a vulnerability as referenced in the mfsa2017-08 advisory.

 - An integer overflow in <code>createImageBitmap()</code> was reported through the Pwn2Own contest. The fix for this vulnerability disables the experimental extensions to the <code>createImageBitmap</code> API.
 This function runs in the content sandbox, requiring a second vulnerability to compromise a user's computer. (CVE-2017-5428)

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 ESR version 52.0.1 or later.
