Mozilla Firefox < 96.0

critical Nessus Plugin ID 156605

Language:

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 96.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-01 advisory.

 - When a worker is shutdown, it was possible to cause script to run late in the lifecycle, at a point after where it should not be possible. (CVE-2022-22763)

 - It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.
 (CVE-2021-4140)

 - A race condition could have allowed bypassing the fullscreen notification which could have lead to a fullscreen window spoof being unnoticed. This bug only affects Firefox for Windows. Other operating systems are unaffected. (CVE-2022-22746)

 - When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could have made the browser unable to leave fullscreen mode. (CVE-2022-22743)

 - When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access causing a potentially exploitable crash. (CVE-2022-22742)

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 96.0 or later.
