Mozilla developers Timothy Nikkel, Ashley Hale, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 105. 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. This vulnerability affects Firefox < 106.

An update of the mozjs package has been released.

The version of Firefox installed on the remote Windows host is prior to 106.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-44 advisory.

  - Mozilla developers Timothy Nikkel, Ashley Hale, and the Mozilla Fuzzing Team reported memory safety bugs     present in Firefox 105. 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-2022-46885)

  - A same-origin policy violation could have allowed the theft of cross-origin URL entries, leaking the     result of a redirect, via <code>performance.getEntries()</code>. (CVE-2022-42927)

  - Certain types of allocations were missing annotations that, if the Garbage Collector was in a specific     state, could have lead to memory corruption and a potentially exploitable crash. (CVE-2022-42928)

  - An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a     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 106.
    (CVE-2022-46881)

  - If a website called <code>window.print()</code> in a particular way, it could cause a denial of service of     the browser, which may persist beyond browser restart depending on the user's session restore settings.
    (CVE-2022-42929)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 106.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-44 advisory.
