Mozilla Firefox < 127.0

critical Nessus Plugin ID 200314

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 127.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-25 advisory.

 - If an out-of-memory condition occurs at a specific point using allocations in the probabilistic heap checker, an assertion could have been triggered, and in rarer situations, memory corruption could have occurred. (CVE-2024-5695)

 - If a specific sequence of actions is performed when opening a new tab, the triggering principal associated with the new tab may have been incorrect. The triggering principal is used to calculate many values, including the <code>Referer</code> and <code>Sec-</code> headers, meaning there is the potential for incorrect security checks within the browser in addition to incorrect or misleading information sent to remote websites. This bug only affects Firefox for Android. Other versions of Firefox are unaffected.
 (CVE-2024-5687)

 - If a garbage collection was triggered at the right time, a use-after-free could have occurred during object transplant. (CVE-2024-5688)

 - In addition to detecting when a user was taking a screenshot (XXX), a website was able to overlay the 'My Shots' button that appeared, and direct the user to a replica Firefox Screenshots page that could be used for phishing. (CVE-2024-5689)

 - By monitoring the time certain operations take, an attacker could have guessed which external protocol handlers were functional on a user's system. (CVE-2024-5690)

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 127.0 or later.
