The version of thunderbird installed on the remote host is prior to 115.11.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2561 advisory.

    A type check was missing when handling fonts in PDF.js, which would allow arbitrary JavaScript execution     in the PDF.js context. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird <     115.11. (CVE-2024-4367)

    If the `browser.privatebrowsing.autostart` preference is enabled, IndexedDB files were not properly     deleted when the window was closed. This preference is disabled by default in Firefox. This vulnerability     affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4767)

    A bug in popup notifications' interaction with WebAuthn made it easier for an attacker to trick a user     into granting permissions. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird     < 115.11. (CVE-2024-4768)

    When importing resources using Web Workers, error messages would distinguish the difference between     `application/javascript` responses and non-script responses.  This could have been abused to learn     information cross-origin. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird     < 115.11. (CVE-2024-4769)

    When saving a page to PDF, certain font styles could have led to a potential use-after-free crash. This     vulnerability affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11. (CVE-2024-4770)

    Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. 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. This vulnerability affects Firefox < 126, Firefox ESR < 115.11, and     Thunderbird < 115.11. (CVE-2024-4777)
