Mozilla developers Gabriele Svelto, Yulia Startsev, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 106. 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*: This advisory was added on December 13th, 2022 after discovering it was inadvertently left out of the original advisory. The fix was included in the original release of Firefox 107. This vulnerability affects Firefox < 107.

An update of the mozjs package has been released.

The version of Firefox installed on the remote Windows host is prior to 107.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-47 advisory.

 This advisory was added on December 13th, 2022 after discovering it was inadvertently left out of the original advisory. The fix was included in the original release of Firefox 107. (CVE-2022-46883)

 - A use-after-free in WebGL extensions could have led to a potentially exploitable crash. 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 107. (CVE-2022-46882)

 - Service Workers should not be able to infer information about opaque cross-origin responses; but timing information for cross-origin media combined with Range requests might have allowed them to determine the presence or length of a media file. (CVE-2022-45403)

 - Through a series of popup and <code>window.print()</code> calls, an attacker can cause a window to go fullscreen without the user seeing the notification prompt, resulting in potential user confusion or spoofing attacks. (CVE-2022-45404)

 - Freeing arbitrary <code>nsIInputStream</code>'s on a different thread than creation could have led to a use-after-free and potentially exploitable crash. (CVE-2022-45405)

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