Synopsis

A web browser installed on the remote Windows host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 102.5. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-48 advisory.

- Mozilla developers Andrew McCreight and Gabriele Svelto reported memory safety bugs present in Firefox 106 and Firefox ESR 102.4. 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-2022-45421)

- If an out-of-memory condition occurred when creating a JavaScript global, a JavaScript realm may be deleted while references to it lived on in a BaseShape. This could lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-45406)

- 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.

Solution

Upgrade to Mozilla Firefox ESR version 102.5 or later.
