"The version of thunderbird installed on the remote host is prior to 91.7.0-2. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2-2022-1779 advisory.

  - In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. (CVE-2022-25315)

  - It may be possible for an attacker to craft an email message that causes Thunderbird to perform an out-of-
    bounds write of one byte when processing the message. This vulnerability affects Thunderbird < 91.6.1.
    (CVE-2022-0566)

  - xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks
    for whether a UTF-8 character is valid in a certain context. (CVE-2022-25235)

  - xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters
    into namespace URIs. (CVE-2022-25236)

  - An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a
    potentially exploitable crash. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and
    Thunderbird < 91.7. (CVE-2022-26381)

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