"The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple
vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - firefox: Possible integer overflow to fix inside XML_Parse in Expat (CVE-2016-9063)

  - firefox: arbitrary code execution and a sandbox escape (CVE-2019-25136)

  - By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject
    stylesheets and bypass Content Security Policy (CSP). This vulnerability affects Firefox < 63.
    (CVE-2018-12398)

  - When a new protocol handler is registered, the API accepts a title argument which can be used to mislead
    users about which domain is registering the new protocol. This may result in the user approving a protocol
    handler that they otherwise would not have. This vulnerability affects Firefox < 63. (CVE-2018-12399)

  - Some special resource URIs will cause a non-exploitable crash if loaded with optional parameters following
    a '?' in the parsed string. This could lead to denial of service (DOS) attacks. This vulnerability affects
    Firefox < 63. (CVE-2018-12401)

  - The internal WebBrowserPersist code does not use correct origin context for a resource being saved. This
    manifests when sub-resources are loaded as part of Save Page As... functionality. For example, a
    malicious page could recover a visitor's Windows username and NTLM hash by including resources otherwise
    unreachable to the malicious page, if they can convince the visitor to save the complete web page.
    Similarly, SameSite cookies are sent on cross-origin requests when the Save Page As... menu item is
    selected to save a page, which can result in saving the wrong version of resources based on those cookies.
    This vulnerability affects Firefox < 63. (CVE-2018-12402)

  - If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content
    warning is not displayed to users. This vulnerability affects Firefox < 63. (CVE-2018-12403)

  - WebExtension content scripts can be loaded into about: pages in some circumstances, in violation of the
    permissions granted to extensions. This could allow an extension to interfere with the loading and usage
    of these pages and use capabilities that were intended to be restricted from extensions. This
    vulnerability affects Firefox < 64. (CVE-2018-18495)

  - Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a
    pipe in the URL field is used within the extension to load multiple pages as a single argument. This could
    allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects
    Firefox < 64. (CVE-2018-18497)

  - In some circumstances, JIT compiled code could have dereferenced a wild pointer value. This could have led
    to an exploitable crash. This vulnerability affects Firefox < 122. (CVE-2024-0744)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package
is installed.");
