The remote Ubuntu 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7991-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of     service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute     arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Memory safety bugs present in 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. This vulnerability was fixed in Firefox 142,     Firefox ESR 140.2, Thunderbird 142, and Thunderbird 140.2. (CVE-2025-9184)

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

The version of Thunderbird installed on the remote macOS or Mac OS X 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)

  - 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 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.

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.
