Memory safety bugs present in Firefox 115. 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 < 116.

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

  - Memory safety bugs present in Firefox 115. 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 < 116. (CVE-2023-4058)

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

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6267-1 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, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2023-4047, CVE-2023-4048,     CVE-2023-4049, CVE-2023-4051, CVE-2023-4053, CVE-2023-4055, CVE-2023-4056, CVE-2023-4057, CVE-2023-4058)

    Max Vlasov discovered that Firefox Offscreen Canvas did not properly track cross-origin tainting. An     attacker could potentially exploit this issue to access image data from another site in violation of same-     origin policy. (CVE-2023-4045)

    Alexander Guryanov discovered that Firefox did not properly update the value of a global variable in WASM     JIT analysis in some circumstances. An attacker could potentially exploit this issue to cause a denial of     service. (CVE-2023-4046)

    Mark Brand discovered that Firefox did not properly validate the size of an untrusted input stream. An     attacker could potentially exploit this issue to cause a denial of service. (CVE-2023-4050)

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 Fedora 38 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-b4b8e4f1b9 advisory.

    - Updated to latest upstream (116.0)

Tenable has extracted the preceding description block directly from the Fedora 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 version of Firefox installed on the remote Windows host is prior to 116.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-29 advisory.

  - Offscreen Canvas did not properly track cross-origin tainting, which could have been used to access image     data from another site in violation of same-origin policy. (CVE-2023-4045)

  - In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This     resulted in incorrect compilation and a potentially exploitable crash in the content process.
    (CVE-2023-4046)

  - A bug in popup notifications delay calculation could have made it possible for an attacker to trick a user     into granting permissions. (CVE-2023-4047)

  - An out-of-bounds read could have led to an exploitable crash when parsing HTML with DOMParser in low     memory situations. (CVE-2023-4048)

  - Race conditions in reference counting code were found through code inspection. These could have resulted     in potentially exploitable use-after-free vulnerabilities. (CVE-2023-4049)

  - In some cases, an untrusted input stream was copied to a stack buffer without checking its size. This     resulted in a potentially exploitable crash which could have led to a sandbox escape. (CVE-2023-4050)

  - A website could have obscured the full screen notification by using the file open dialog. This could have     led to user confusion and possible spoofing attacks. (CVE-2023-4051)

  - The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any     files in that directory would be recursively deleted with the permissions of the uninstalling user     account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary     file deletion controlled by the non-privileged user.  This bug only affects Firefox on Windows. Other     operating systems are unaffected. (CVE-2023-4052)

  - A website could have obscured the full screen notification by using a URL with a scheme handled by an     external program, such as a mailto URL. This could have led to user confusion and possible spoofing     attacks. (CVE-2023-4053)

  - When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code.
    This bug only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2023-4054)

  - When the number of cookies per domain was exceeded in <code>document.cookie</code>, the actual cookie jar     sent to the host was no longer consistent with expected cookie jar state. This could have caused requests     to be sent with some cookies missing. (CVE-2023-4055)

  - Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and     Thunderbird 102.13. 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-2023-4056)
