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 108.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-51 advisory.

 - An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited.
 (CVE-2022-46871)

 - An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary files via clipboard-related IPC messages. This bug only affects Firefox for Linux. Other operating systems are unaffected. (CVE-2022-46872)

 - Because Firefox did not implement the <code>unsafe-hashes</code> CSP directive, an attacker who was able to inject markup into a page otherwise protected by a Content Security Policy may have been able to inject executable script. This would be severely constrained by the specified Content Security Policy of the document. (CVE-2022-46873)

 - A file with a long filename could have had its filename truncated to remove the valid extension, leaving a malicious extension in its place. This could have potentially led to user confusion and the execution of malicious code. (CVE-2022-46874)

 - The executable file warning was not presented when downloading .atloc and .ftploc files, which can run commands on a user's computer. Note: This issue only affected Mac OS operating systems. Other operating systems are unaffected. (CVE-2022-46875)

 - By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in potential user confusion or spoofing attacks. (CVE-2022-46877)

 - Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107 and Firefox ESR 102.5. 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-2022-46878)

 - Mozilla developers and community members Lukas Bernhard, Gabriele Svelto, Randell Jesup, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 107. 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-2022-46879)

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 108.0 or later.
