The remote Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-2a5256e2a3 advisory.

  • 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. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32205)

  • An out-of-bound read could have led to a crash in the RLBox Expat driver. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32206)

  • A missing delay in popup notifications could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32207)

  • Service workers could reveal script base URL due to dynamic import(). This vulnerability affects Firefox < 113. (CVE-2023-32208)

  • A maliciously crafted favicon could have led to an out of memory crash. This vulnerability affects Firefox < 113. (CVE-2023-32209)

  • Documents were incorrectly assuming an ordering of principal objects when ensuring we were loading an appropriately privileged principal. In certain circumstances it might have been possible to cause a document to be loaded with a higher privileged principal than intended. This vulnerability affects Firefox < 113. (CVE-2023-32210)

  • A type checking bug would have led to invalid code being compiled. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32211)

  • An attacker could have positioned a <code>datalist</code> element to obscure the address bar. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32212)

  • When reading a file, an uninitialized value could have been used as read limit. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32213)

  • Protocol handlers ms-cxh and ms-cxh-full could have been leveraged to trigger a denial of service.
    Note: This attack only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11. (CVE-2023-32214)

  • 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. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.
    (CVE-2023-32215)

  • Memory safety bugs present in Firefox 112. 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 < 113. (CVE-2023-32216)

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