An update of the mozjs package has been released.

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

  - 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)

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

  - 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)

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 mozilla-firefox installed on the remote host is prior to 102.8.0esr / 110.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-045-01 advisory.

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - 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)

  - Mozilla developers Philipp and Gabriele Svelto reported memory safety bugs present in 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-2023-25746)

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 mozilla-thunderbird installed on the remote host is prior to 102.8.0. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-047-01 advisory.

  - If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to     process and display the message, which could cause Thunderbird's user interface to lock up and no longer     respond to the user's actions. An attacker could send a crafted message with this structure to attempt a     DoS attack.  (CVE-2023-0616)

  - 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)

The version of thunderbird installed on the remote host is prior to 102.8.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2023-1983 advisory.

    2024-02-15: CVE-2023-0616 was added to this advisory.

    If a MIME email combines OpenPGP and OpenPGP MIME data in a certain way Thunderbird repeatedly attempts to     process and display the message, which could cause Thunderbird's user interface to lock up and no longer     respond to the user's actions. An attacker could send a crafted message with this structure to attempt a     DoS attack. (CVE-2023-0616)

    firefox-esr , thunderbird and nss only are affected by this package. (CVE-2023-0767)

    hb-ot-layout-gsubgpos.hh in HarfBuzz through 6.0.0 allows attackers to trigger O(n^2) growth via     consecutive marks during the process of looking back for base glyphs when attaching marks.
    (CVE-2023-25193)

    The Mozilla Foundation Security Advisory describes this flaw as:

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

    The Mozilla Foundation Security Advisory describes this flaw as:

    Permission prompts for opening external schemes were only shown for `ContentPrincipals` resulting in     extensions being able to open them without user interaction via `ExpandedPrincipals`.

    (CVE-2023-25730)

    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)

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

    The Mozilla Foundation Security Advisory describes this flaw as:

    After downloading a Windows `.url` 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.
