Mozilla Firefox < 65.0

critical Nessus Plugin ID 121511

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 65.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-01 advisory.

- Mozilla developers and community members Arthur Iakab, Christoph Diehl, Christian Holler, Kalel, Emilio Cobos lvarez, Cristina Coroiu, Noemi Erli, Natalia Csoregi, Julian Seward, Gary Kwong, Tyson Smith, Yaron Tausky, and Ronald Crane reported memory safety bugs present in Firefox 64. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. (CVE-2018-18502)

- An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. (CVE-2018-18505)

- A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. (CVE-2018-18500)

- A crash and out-of-bounds read can occur when the buffer of a texture client is freed while it is still in use during graphic operations. This results in a potentially exploitable crash and the possibility of reading from the memory of the freed buffers. (CVE-2018-18504)

- When JavaScript is used to create and manipulate an audio buffer, a potentially exploitable crash may occur because of a compartment mismatch in some situations. (CVE-2018-18503)

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

Solution

Upgrade to Mozilla Firefox version 65.0 or later.
