In some instances, the user-agent would allow push requests which lacked a valid VAPID even though the push manager subscription defined one. This could allow empty messages to be sent from unauthorized parties. *This bug only affects Firefox on Android.* This vulnerability affects Firefox < 121.

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

    (CVE-2023-6868)

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

The remote host is affected by the vulnerability described in GLSA-202401-10 (Mozilla Firefox: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox. Please review the CVE identifiers     referenced below for details.

Tenable has extracted the preceding description block directly from the Gentoo Linux 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 39 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2023-9de52d46bd advisory.

    Update NSS to 3.95     Update Firefox to 121.0

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

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.

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 macOS or Mac OS X 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)
