Mozilla Firefox < 135.0

high Nessus Plugin ID 214964

Synopsis

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

Description

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 135.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-07 advisory.

 - Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 115.19, Firefox ESR 128.6, Thunderbird 115.19, and Thunderbird 128.6. 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-2025-1016)

 - An attacker could have caused a use-after-free via crafted XSLT data, leading to a potentially exploitable crash. (CVE-2025-1009)

 - An attacker could have caused a use-after-free via the Custom Highlight API, leading to a potentially exploitable crash. (CVE-2025-1010)

 - The fullscreen notification is prematurely hidden when fullscreen is re-requested quickly by the user.
 This could have been leveraged to perform a potential spoofing attack. (CVE-2025-1018)

 - A bug in WebAssembly code generation could have lead to a crash. It may have been possible for an attacker to leverage this to achieve code execution. (CVE-2025-1011)

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 135.0 or later.
