Mozilla Firefox ESR < 91.11

critical Nessus Plugin ID 162605

Synopsis

A web browser installed on the remote macOS or Mac OS X host is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 91.11. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-25 advisory.

- The Mozilla Fuzzing Team reported potential vulnerabilities present in Firefox 101 and Firefox ESR 91.10.
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-2022-34484)

- Session history navigations may have led to a use-after-free and potentially exploitable crash.
(CVE-2022-34470)

- A malicious website that could create a popup could have resized the popup to overlay the address bar with its own content, resulting in potential user confusion or spoofing attacks. This bug only affects Firefox for Linux. Other operating systems are unaffected. (CVE-2022-34479)

- An iframe that was not permitted to run scripts could do so if the user clicked on a <code>javascript:</code> link. (CVE-2022-34468)

- In the <code>nsTArrayImpl::ReplaceElementsAt()</code> function, an integer overflow could have occurred when the number of elements to replace was too large for the container. (CVE-2022-34481)

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 91.11 or later.
