Synopsis

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

Description

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 152.0.4. It is, therefore, affected by a vulnerability as referenced in the mfsa2026-62 advisory.

 - Memory safety bugs present in Firefox 152.0.3. 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.

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 version 152.0.4 or later.
