The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:0817 advisory.

  - Mozilla: User Interface lockup with messages combining S/MIME and OpenPGP (CVE-2023-0616)

  - Mozilla: Content security policy leak in violation reports using iframes (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. This vulnerability affects Firefox < 110,     Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25729)

  - Mozilla: Screen hijack via browser fullscreen mode (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. This     vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25732)

  - 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. This     vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8. (CVE-2023-25735)

  - An invalid downcast from <code>nsTextNode</code> to <code>SVGElement</code> could have lead to undefined     behavior. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.
    (CVE-2023-25737)

  - 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>. This vulnerability affects Firefox < 110, Thunderbird <     102.8, and Firefox ESR < 102.8. (CVE-2023-25739)

  - Mozilla: Web Crypto ImportKey crashes tab (CVE-2023-25742)

  - Mozilla: Fullscreen notification not shown in Firefox Focus (CVE-2023-25743)

  - Mmemory 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. This vulnerability affects Firefox < 110 and Firefox ESR < 102.8. (CVE-2023-25744)

  - 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. This     vulnerability affects Thunderbird < 102.8 and Firefox ESR < 102.8. (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.

  - 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.

  - Mozilla: Fullscreen notification not shown in Firefox Focus (CVE-2023-25743)

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

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

The version of Firefox ESR installed on the remote Windows host is prior to 102.8. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-06 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)

  - 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)

    (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)
