The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An attacker could have written a value to the first element in a zero-length JavaScript array. Although     the array was zero-length, the value was not written to an invalid memory address. This vulnerability     affects Firefox < 104. (CVE-2022-38475)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5581-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, spoof the     contents of the addressbar, bypass security restrictions, or execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

The remote host is affected by the vulnerability described in GLSA-202208-37 (Mozilla Firefox: Multiple Vulnerabilities)

  - 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.  (CVE-2022-38472)

  - Mozilla: Cross-origin XSLT Documents would have inherited the parent's permissions (CVE-2022-38473)

  - A website that had permission to access the microphone could record audio without the audio notification     being shown. This bug does not allow the attacker to bypass the permission prompt - it only affects the     notification shown once permission has been granted.<br />This bug only affects Firefox for Android. Other     operating systems are unaffected.  (CVE-2022-38474)

  - An attacker could have written a value to the first element in a zero-length JavaScript array. Although     the array was zero-length, the value was not written to an invalid memory address.  (CVE-2022-38475)

  - A data race could occur in the <code>PK11ChangePW</code> function, potentially leading to a use-after-free     vulnerability.  In Thunderbird, this lock protected the data when a user changed their master password.
    (CVE-2022-38476)

  - Mozilla developer Nika Layzell and the Mozilla Fuzzing Team reported memory safety bugs present in     Thunderbird 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.  (CVE-2022-38477)

  - Members the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.1 and Thunderbird     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.  (CVE-2022-38478)

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

An update of the mozjs package has been released.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 104.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2022-33 advisory.

  - 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. (CVE-2022-38478)

  - 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. (CVE-2022-38472)

  - A cross-origin iframe referencing an XSLT document would inherit the parent domain's permissions (such as     microphone or camera access). (CVE-2022-38473)

  - A website that had permission to access the microphone could record audio without the audio notification     being shown. This bug does not allow the attacker to bypass the permission prompt - it only affects the     notification shown once permission has been granted.<br />This bug only affects Firefox for Android.
