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 105.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-40 advisory.

 - Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 104 and Firefox ESR 102.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. (CVE-2022-40962)

 - An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash.
 (CVE-2022-3266)

 - During iframe navigation, certain pages did not have their FeaturePolicy fully initialized leading to a bypass that leaked device permissions into untrusted subdocuments. (CVE-2022-40959)

 - Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after- free causing a potentially exploitable crash. (CVE-2022-40960)

 - A missing check related to tex units could have led to a use-after-free and potentially exploitable crash.<br />Note: This advisory was added on December 13th, 2022 after we better understood the impact of the issue. The fix was included in the original release of Firefox 105. (CVE-2022-46880)

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 105.0 or later.
