Mozilla Firefox < 119.0

Synopsis

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

Description

The version of Firefox installed on the remote Windows host is prior to 119.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-45 advisory.

- Memory safety bugs present in Firefox 118. 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-2023-5731)

- It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by the user due to an insufficient activation-delay. (CVE-2023-5721)

- Using iterative requests an attacker was able to learn the size of an opaque response, as well as the contents of a server-supplied Vary header. (CVE-2023-5722)

- An attacker with temporary script access to a site could have set a cookie containing invalid characters using <code>document.cookie</code> that could have led to unknown errors. (CVE-2023-5723)

- Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led to a crash. (CVE-2023-5724)

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 119.0 or later.
