"The version of Firefox installed on the remote macOS or Mac OS X host is prior to 110.0. It is, therefore, affected by
multiple vulnerabilities as referenced in the mfsa2023-05 advisory.

  - The <code>Content-Security-Policy-Report-Only</code> header could allow an attacker to leak a child
    iframe's unredacted URI when interaction with that iframe triggers a redirect. (CVE-2023-25728)

  - A background script invoking <code>requestFullscreen</code> and then blocking the main thread could force
    the browser into fullscreen mode indefinitely, resulting in potential user confusion or spoofing attacks.
    (CVE-2023-25730)

  - A lack of in app notification for entering fullscreen mode could have lead to a malicious website spoofing
    browser chrome. This bug only affects Firefox Focus. Other versions of Firefox are unaffected.
    (CVE-2023-25743)

  - An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory
    writes via PKCS 12 Safe Bag attributes being mishandled. (CVE-2023-0767)

  - Cross-compartment wrappers wrapping a scripted proxy could have caused objects from other compartments to
    be stored in the main compartment resulting in a use-after-free after unwrapping the proxy.
    (CVE-2023-25735)

  - An invalid downcast from <code>nsTextNode</code> to <code>SVGElement</code> could have lead to undefined
    behavior. (CVE-2023-25737)

  - Members of the <code>DEVMODEW</code> struct set by the printer device driver weren't being validated and
    could have resulted in invalid values which in turn would cause the browser to attempt out of bounds
    access to related variables. This bug only affects Firefox on Windows. Other operating systems are
    unaffected. (CVE-2023-25738)

  - Module load requests that failed were not being checked as to whether or not they were cancelled causing a
    use-after-free in <code>ScriptLoadContext</code>. (CVE-2023-25739)

  - Permission prompts for opening external schemes were only shown for <code>ContentPrincipals</code>
    resulting in extensions being able to open them without user interaction via
    <code>ExpandedPrincipals</code>. This could lead to further malicious actions such as downloading files or
    interacting with software already installed on the system. (CVE-2023-25729)

  - When encoding data from an <code>inputStream</code> in <code>xpcom</code> the size of the input being
    encoded was not correctly calculated potentially leading to an out of bounds memory write.
    (CVE-2023-25732)

  - After downloading a Windows <code>.url</code> shortcut from the local filesystem, an attacker could supply
    a remote path that would lead to unexpected network requests from the operating system.  This also had the
    potential to leak NTLM credentials to the resource. This bug only affects Firefox on Windows. Other
    operating systems are unaffected. (CVE-2023-25734)

  - After downloading a Windows <code>.scf</code> script from the local filesystem, an attacker could supply a
    remote path that would lead to unexpected network requests from the operating system. This also had the
    potential to leak NTLM credentials to the resource. This bug only affects Firefox for Windows. Other
    operating systems are unaffected. (CVE-2023-25740)

  - Due to URL previews in the network panel of developer tools improperly storing URLs, query parameters
    could potentially be used to overwrite global objects in privileged code. (CVE-2023-25731)

  - The return value from <code>gfx::SourceSurfaceSkia::Map()</code> wasn't being verified which could have
    potentially lead to a null pointer dereference. (CVE-2023-25733)

  - An invalid downcast from <code>nsHTMLDocument</code> to <code>nsIContent</code> could have lead to
    undefined behavior. (CVE-2023-25736)

  - When dragging and dropping an image cross-origin, the image's size could potentially be leaked. This
    behavior was shipped in 109 and caused web compatibility problems as well as this security concern, so the
    behavior was disabled until further review. (CVE-2023-25741)

  - When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab
    to crash. (CVE-2023-25742)

  - Mozilla developers Kershaw Chang and the Mozilla Fuzzing Team reported memory safety bugs present in
    Firefox 109 and Firefox ESR 102.7. 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-2023-25744)

  - Mozilla developers Timothy Nikkel, Gabriele Svelto, Jeff Muizelaar and the Mozilla Fuzzing Team reported
    memory safety bugs present in Firefox 109. 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-2023-25745)
