vendor_unpatched cve-2025-11716: Unpatched CVEs for Ubuntu Linux (cve-2025-11716)

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2025-64d57de006 advisory.

    - Added fix for mzbz#1990430 (crashes)

    ----

    - Updated to latest upstream (144.0)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 144.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-81 advisory.

  - A malicious page could have used the type attribute of an OBJECT tag to override the default browser     behavior when encountering a web resource served without a content-type. This could have contributed to an     XSS on a site that unsafely serves files without a content-type header. (CVE-2025-11712)

  - Use-after-free in MediaTrackGraphImpl::GetInstance() (CVE-2025-11708)

  - A compromised web process was able to trigger out of bounds reads and writes in a more privileged process     using manipulated WebGL textures. (CVE-2025-11709)

  - A compromised web process using malicious IPC messages could have caused the privileged browser process to     reveal blocks of its memory to the compromised process. (CVE-2025-11710)

  - There was a way to change the value of JavaScript Object properties that were supposed to be non-     writeable. (CVE-2025-11711)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Firefox installed on the remote Windows host is prior to 144.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-81 advisory.
