The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2021:5013 advisory.

  - Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith,     Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. 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 < 95, Firefox ESR < 91.4.0, and     Thunderbird < 91.4.0. (CVE-2021-4129)

  - Under certain circumstances, asynchronous functions could have caused a navigation to fail but expose the     target URL. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43536)

  - An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory     leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR <     91.4.0, and Firefox < 95. (CVE-2021-43537)

  - By misusing a race in our notification code, an attacker could have forcefully hidden the notification for     pages that had received full screen and pointer lock access, which could have been used for spoofing     attacks. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43538)

  - Failure to correctly record the location of live pointers across wasm instance calls resulted in a GC     occurring within the call not tracing those live pointers. This could have led to a use-after-free causing     a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0,     and Firefox < 95. (CVE-2021-43539)

  - When invoking protocol handlers for external protocols, a supplied parameter URL containing spaces was not     properly escaped. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
    (CVE-2021-43541)

  - Using XMLHttpRequest, an attacker could have identified installed applications by probing error messages     for loading external protocols. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43542)

  - Documents loaded with the CSP sandbox directive could have escaped the sandbox's script restriction by     embedding additional content. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and     Firefox < 95. (CVE-2021-43543)

  - Using the Location API in a loop could have caused severe application hangs and crashes. This     vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. (CVE-2021-43545)

  - It was possible to recreate previous cursor spoofing attacks against users with a zoomed native cursor.
    This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95. (CVE-2021-43546)

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 95.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2021-52 advisory.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5248-1 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, trick a user into accepting unwanted permissions, conduct header     splitting attacks, conduct spoofing attacks, bypass security restrictions, confuse the user, or execute     arbitrary code. (CVE-2021-4129, CVE-2021-4140, CVE-2021-29981, CVE-2021-29982, CVE-2021-29987,     CVE-2021-29991, CVE-2021-38495, CVE-2021-38496, CVE-2021-38497, CVE-2021-38498, CVE-2021-38500,     CVE-2021-38501, CVE-2021-38503, CVE-2021-38504, CVE-2021-38506, CVE-2021-38507, CVE-2021-38508,     CVE-2021-38509, CVE-2021-43534, CVE-2021-43535, CVE-2021-43536, CVE-2021-43537, CVE-2021-43538,     CVE-2021-43539, CVE-2021-43541, CVE-2021-43542, CVE-2021-43543, CVE-2021-43545, CVE-2021-43656,     CVE-2022-22737, CVE-2022-22738, CVE-2022-22739, CVE-2022-22740, CVE-2022-22741, CVE-2022-22742,     CVE-2022-22743, CVE-2022-22745, CVE-2022-22747, CVE-2022-22748, CVE-2022-22751)

    It was discovered that Thunderbird ignored the configuration to require STARTTLS for an SMTP connection. A     person-in-the-middle could potentially exploit this to perform a downgrade attack in order to intercept     messages or take control of a session. (CVE-2021-38502)

    It was discovered that JavaScript was unexpectedly enabled in the composition area. An attacker could     potentially exploit this in combination with another vulnerability, with unspecified impacts.
    (CVE-2021-43528)

    A buffer overflow was discovered in the Matrix chat library bundled with Thunderbird. An attacker could     potentially exploit this to cause a denial of service, or execute arbitrary code. (CVE-2021-44538)

    It was discovered that Thunderbird's OpenPGP integration only considered the inner signed message when     checking signature validity in a message that contains an additional outer MIME layer. An attacker could     potentially exploit this to trick the user into thinking that a message has a valid signature.
    (CVE-2021-4126)
