The remote Oracle Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2023-3143 advisory.

  • A missing delay in popup notifications could have made it possible for an attacker to trick a user into granting permissions. (CVE-2023-32207)

  • Mozilla developers and community members Gabriele Svelto, Andrew Osmond, Emily McDonough, Sebastian Hengst, Andrew McCreight and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 112 and Firefox ESR 102.10. 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-2023-32215)

  • An attacker could have positioned a <code>datalist</code> element to obscure the address bar.
    (CVE-2023-32212)

  • In multiple cases browser prompts could have been obscured by popups controlled by content. These could have led to potential user confusion and spoofing attacks. (CVE-2023-32205)

  • An out-of-bound read could have led to a crash in the RLBox Expat driver. (CVE-2023-32206)

  • A type checking bug would have led to invalid code being compiled. (CVE-2023-32211)

  • When reading a file, an uninitialized value could have been used as read limit. (CVE-2023-32213)

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