The remote MiracleLinux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the AXSA:2024-7400:04 advisory.

    * Mozilla: Heap-buffer-overflow affecting WebGL <code>DrawElementsInstanced</code> method with Mesa VM     driver (CVE-2023-6856)
      * Mozilla: Memory safety bugs fixed in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6     (CVE-2023-6864)
      * Mozilla: Potential exposure of uninitialized data in <code>EncryptingOutputStream</code>     (CVE-2023-6865)
      * Mozilla: Symlinks may resolve to smaller than expected buffers (CVE-2023-6857)
      * Mozilla: Heap buffer overflow in <code>nsTextFragment</code> (CVE-2023-6858)
      * Mozilla: Use-after-free in PR_GetIdentitiesLayer (CVE-2023-6859)
      * Mozilla: Potential sandbox escape due to <code>VideoBridge</code> lack of texture validation     (CVE-2023-6860)
      * Mozilla: Heap buffer overflow affected <code>nsWindow::PickerOpen(void)</code> in headless mode     (CVE-2023-6861)
      * Mozilla: Use-after-free in <code>nsDNSService</code> (CVE-2023-6862)
      * Mozilla: Clickjacking permission prompts using the popup transition (CVE-2023-6867)
      * Mozilla: Undefined behavior in <code>ShutdownObserver()</code> (CVE-2023-6863)

Tenable has extracted the preceding description block directly from the MiracleLinux 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 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 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 < 115.6, Thunderbird < 115.6, and     Firefox < 121. (CVE-2023-6864)

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

The version of Firefox installed on the remote Windows host is prior to 121.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-56 advisory.

  - Memory safety bugs present in Firefox 120. 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-2023-6873)

  - The WebGL <code>DrawElementsInstanced</code> method was susceptible to a heap buffer overflow when used on     systems with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and     sandbox escape. (CVE-2023-6856)

  - Multiple NSS NIST curves were susceptible to a side-channel attack known as Minerva. This attack could     potentially allow an attacker to recover the private key. (CVE-2023-6135)

  - <code>EncryptingOutputStream</code> was susceptible to exposing uninitialized data. This issue could only     be abused in order to write data to a local disk which may have implications for private browsing mode.
    (CVE-2023-6865)

  - When resolving a symlink, a race may occur where the buffer passed to <code>readlink</code> may actually     be smaller than necessary.  This bug only affects Firefox on Unix-based operating systems (Android, Linux,     MacOS). Windows is unaffected. (CVE-2023-6857)

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 packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-983329cf45 advisory.

    Update NSS to 3.95     Update to Firefox 121.0

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