Mozilla Firefox ESR < 52.0.1 CreateImageBitmap RCE (macOS)

High Nessus Plugin ID 99124

Synopsis

The remote macOS or Mac OS X host contains a web browser that is affected by a remote code execution vulnerability.

Description

The version of Mozilla Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.0.1. It is, therefore, affected by an integer overflow condition in the nsGlobalWindow::CreateImageBitmap() function within file dom/base/nsGlobalWindow.cpp due to improper validation of certain input. An unauthenticated, remote attacker can exploit this to corrupt memory, possibly resulting in the execution of arbitrary code.

Note that this function runs in the content sandbox, requiring a second vulnerability to compromise a user's computer.

Solution

Upgrade to Mozilla Firefox ESR version 52.0.1 or later.
