Mozilla Firefox ESR < 115.14

critical Nessus Plugin ID 205012

Language:

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 115.14. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-34 advisory.

 - Unexpected marking work at the start of sweeping could have led to a use-after-free. (CVE-2024-7527)

 - Insufficient checks when processing graphics shared memory could have led to memory corruption. This could be leveraged by an attacker to perform a sandbox escape. (CVE-2024-7519)

 - Incomplete WebAssembly exception handing could have led to a use-after-free. (CVE-2024-7521)

 - Editor code failed to check an attribute value. This could have led to an out-of-bounds read.
 (CVE-2024-7522)

 - Firefox adds web-compatibility shims in place of some tracking scripts blocked by Enhanced Tracking Protection. On a site protected by Content Security Policy in strict-dynamic mode, an attacker able to inject an HTML element could have used a DOM Clobbering attack on some of the shims and achieved XSS, bypassing the CSP strict-dynamic protection. (CVE-2024-7524)

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 115.14 or later.
