The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2022-5469 advisory.

  • If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes on a JavaScript object, leading to privileged code execution. (CVE-2022-2200)

  • If there was a PAC URL set and the server that hosts the PAC was not reachable, OCSP requests would have been blocked, resulting in incorrect error pages being shown. (CVE-2022-34472)

  • A malicious website that could create a popup could have resized the popup to overlay the address bar with its own content, resulting in potential user confusion or spoofing attacks. This bug only affects Thunderbird for Linux. Other operating systems are unaffected. (CVE-2022-34479)

  • In the <code>nsTArrayImpl::ReplaceElementsAt()</code> function, an integer overflow could have occurred when the number of elements to replace was too large for the container. (CVE-2022-34481)

  • The Mozilla Fuzzing Team reported potential vulnerabilities present in Thunderbird 91.10. 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-2022-34484)

  • An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and in doing so bypass a page’s Content Security Policy. (CVE-2022-31744)

  • An iframe that was not permitted to run scripts could do so if the user clicked on a <code>javascript:</code> link. (CVE-2022-34468)

  • Navigations between XML documents may have led to a use-after-free and potentially exploitable crash.
    (CVE-2022-34470)

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