The remote AlmaLinux 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2025:14417 advisory.

    * firefox: thunderbird: Denial-of-service due to out-of-memory in the Graphics: WebRender component     (CVE-2025-9182)
      * thunderbird: firefox: Sandbox escape due to invalid pointer in the Audio/Video: GMP component     (CVE-2025-9179)
      * thunderbird: firefox: Same-origin policy bypass in the Graphics: Canvas2D component (CVE-2025-9180)
      * thunderbird: firefox: Uninitialized memory in the JavaScript Engine component (CVE-2025-9181)
      * thunderbird: firefox: Memory safety bugs fixed in Firefox ESR 115.27, Firefox ESR 128.14, Thunderbird     ESR 128.14, Firefox ESR 140.2, Thunderbird ESR 140.2, Firefox 142 and Thunderbird 142 (CVE-2025-9185)

Tenable has extracted the preceding description block directly from the AlmaLinux 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 FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the f994cea5-7eb0-11f0-ba14-b42e991fc52e advisory.

    security@mozilla.org reports:
    'Denial-of-service due to out-of-memory in the               Graphics: WebRender component.'

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Denial-of-service due to out-of-memory in the Graphics: WebRender component. This vulnerability affects     Firefox < 142, Firefox ESR < 140.2, Thunderbird < 142, and Thunderbird < 140.2. (CVE-2025-9182)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 140.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-67 advisory.

  - Memory safety bugs present in Firefox ESR 115.26, Firefox ESR 128.13, Thunderbird ESR 128.13, Firefox ESR     140.1, Thunderbird ESR 140.1, Firefox 141 and Thunderbird 141. 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-2025-9185)

  - An attacker was able to perform memory corruption in the GMP process which processes encrypted media. This     process is also heavily sandboxed, but represents slightly different privileges from the content process.
    (CVE-2025-9179)

  - Same-origin policy bypass in the Graphics: Canvas2D component. (CVE-2025-9180)

  - Uninitialized memory in the JavaScript Engine component. (CVE-2025-9181)

  - Denial-of-service due to out-of-memory in the Graphics: WebRender component. (CVE-2025-9182)

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 142.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-64 advisory.

  - Memory safety bugs present in Firefox 141 and Thunderbird 141. 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-2025-9187)

  - An attacker was able to perform memory corruption in the GMP process which processes encrypted media. This     process is also heavily sandboxed, but represents slightly different privileges from the content process.
    (CVE-2025-9179)

  - Same-origin policy bypass in the Graphics: Canvas2D component. (CVE-2025-9180)

  - Uninitialized memory in the JavaScript Engine component. (CVE-2025-9181)

  - Spoofing issue in the Address Bar component of Firefox Focus for Android. (CVE-2025-9186)

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 Thunderbird installed on the remote Windows host is prior to 142.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-70 advisory.

  - Memory safety bugs present in Firefox 141 and Thunderbird 141. 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-2025-9187)
