The version of Firefox installed on the remote Windows host is prior to 124.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2024-12 advisory.

  - An attacker could have leveraged the Windows Error Reporter to run arbitrary code on the system escaping     the sandbox. Note: This issue only affected Windows operating systems. Other operating systems are     unaffected. (CVE-2024-2605)

  - Passing invalid data could have led to invalid wasm values being created, such as arbitrary integers     turning into pointer values. (CVE-2024-2606)

  - Return registers were overwritten which could have allowed an attacker to execute arbitrary code. Note:
    This issue only affected Armv7-A systems. Other operating systems are unaffected. (CVE-2024-2607)

  - <code>AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding()</code> and     <code>AppendEncodedCharacters()</code> could have experienced integer overflows, causing underallocation     of an output buffer leading to an out of bounds write. (CVE-2024-2608)

  - NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could     potentially allow an attacker to recover the private data. (CVE-2023-5388)

  - The permission prompt input delay could have expired while the window is not in focus, which made the     prompt vulnerable to clickjacking by malicious websites. (CVE-2024-2609)

  - Using a markup injection an attacker could have stolen nonce values. This could have been used to bypass     strict content security policies. (CVE-2024-2610)

  - A missing delay on when pointer lock was used could have allowed a malicious page to trick a user into     granting permissions. (CVE-2024-2611)

  - If an attacker could find a way to trigger a particular code path in <code>SafeRefPtr</code>, it could     have triggered a crash or potentially be leveraged to achieve code execution. (CVE-2024-2612)

  - Data was not properly sanitized when decoding a QUIC ACK frame; this could have led to unrestricted memory     consumption and a crash. (CVE-2024-2613)

  - Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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-2024-2614)

  - Memory safety bugs present in Firefox 123. 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.

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6703-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2024-2609, CVE-2024-2611,     CVE-2024-2614, CVE-2024-2615)

    Hubert Kario discovered that Firefox had a timing side-channel when

    performing RSA decryption. A remote attacker could possibly use this

    issue to recover sensitive information. (CVE-2023-5388)

    It was discovered that Firefox did not properly handle WASM register values in some circumstances. An     attacker could potentially exploit this issue to cause a denial of service. (CVE-2024-2606)

    Gary Kwong discovered that Firefox incorrectly updated return registers for JIT code on Armv7-A systems.
    An attacker could potentially exploit

    this issue to execute arbitrary code. (CVE-2024-2607)

    cause a denial of service. (CVE-2024-2608)

    Georg Felber and Marco Squarcina discovered that Firefox incorrectly

    handled html and body tags. An attacker who was able to inject markup into

    a page otherwise protected by a Content Security Policy may have been able

    obtain sensitive information. (CVE-2024-2610)

    Ronald Crane discovered a use-after-free in Firefox when handling code in SafeRefPtr. An attacker could     potentially exploit this issue to cause a

    denial of service, or execute arbitrary code. (CVE-2024-2612)

    Max Inden discovered that Firefox incorrectly handled QUIC ACK frame

    decoding. A attacker could potentially exploit this issue to cause a
