The remote Ubuntu 20.04 LTS / 22.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6995-1 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. (CVE-2024-7521, CVE-2024-7526, CVE-2024-7527, CVE-2024-7529, CVE-2024-8382)

    It was discovered that Thunderbird did not properly manage certain memory operations when processing     graphics shared memory. An attacker could potentially exploit this issue to escape the sandbox.
    (CVE-2024-7519)

    Irvan Kurniawan discovered that Thunderbird did not properly check an attribute value in the editor     component, leading to an out-of-bounds read vulnerability. An attacker could possibly use this issue to     cause a denial of service or expose sensitive information. (CVE-2024-7522)

    Rob Wu discovered that Thunderbird did not properly check permissions when creating a StreamFilter. An     attacker could possibly use this issue to modify response body of requests on any site using a web     extension. (CVE-2024-7525)

    Nils Bars discovered that Thunderbird contained a type confusion vulnerability when performing certain     property name lookups. An attacker could potentially exploit this issue to cause a denial of service, or     execute arbitrary code. (CVE-2024-8381)

    It was discovered that Thunderbird did not properly manage memory during garbage collection. An attacker     could potentially exploit this issue to cause a denial of service, or execute arbitrary code.
    (CVE-2024-8384)

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.
