"The version of firefox installed on the remote host is prior to 91.13.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2023-012 advisory.

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 102. 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 ESR < 102.1, Firefox <
    103, and Thunderbird < 102.1. (CVE-2022-2505)

  - When visiting directory listings for `chrome://` URLs as source text, some parameters were reflected. This
    vulnerability affects Firefox ESR < 102.1, Firefox ESR < 91.12, Firefox < 103, Thunderbird < 102.1, and
    Thunderbird < 91.12. (CVE-2022-36318)

  - When combining CSS properties for overflow and transform, the mouse cursor could interact with different
    coordinates than displayed. This vulnerability affects Firefox ESR < 102.1, Firefox ESR < 91.12, Firefox <
    103, Thunderbird < 102.1, and Thunderbird < 91.12. (CVE-2022-36319)

  - An attacker could have abused XSLT error handling to associate attacker-controlled content with another
    origin which was displayed in the address bar. This could have been used to fool the user into submitting
    data intended for the spoofed origin. This vulnerability affects Thunderbird < 102.2, Thunderbird < 91.13,
    Firefox ESR < 91.13, Firefox ESR < 102.2, and Firefox < 104. (CVE-2022-38472)

  - A cross-origin iframe referencing an XSLT document would inherit the parent domain's permissions (such as
    microphone or camera access). This vulnerability affects Thunderbird < 102.2, Thunderbird < 91.13, Firefox
    ESR < 91.13, Firefox ESR < 102.2, and Firefox < 104. (CVE-2022-38473)

  - A data race could occur in the <code>PK11_ChangePW</code> function, potentially leading to a use-after-
    free vulnerability. In Firefox, this lock protected the data when a user changed their master password.
    This vulnerability affects Firefox ESR < 102.2 and Thunderbird < 102.2. (CVE-2022-38476)

  - Mozilla developer Nika Layzell and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox
    103 and Firefox ESR 102.1. 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 ESR < 102.2, Thunderbird < 102.2, and Firefox < 104. (CVE-2022-38477)

  - Members the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 103, Firefox ESR 102.1,
    and Firefox ESR 91.12. 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
    Thunderbird < 102.2, Thunderbird < 91.13, Firefox ESR < 91.13, Firefox ESR < 102.2, and Firefox < 104.
