"The version of firefox installed on the remote host is prior to 115.4.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2023-017 advisory.

  - A potential use-after-free vulnerability existed in SVG Images if the Refresh Driver was destroyed at an
    inopportune time. This could have lead to memory corruption or a potentially exploitable crash. *Note*:
    This advisory was added on December 13th, 2022 after discovering it was inadvertently left out of the
    original advisory. The fix was included in the original release of Firefox 106. This vulnerability affects
    Firefox < 106. (CVE-2022-46884)

  - When Firefox is configured to block storage of all cookies, it was still possible to store data in
    localstorage by using an iframe with a source of 'about:blank'. This could have led to malicious websites
    storing tracking data without permission. This vulnerability affects Firefox < 115. (CVE-2023-3482)

  - Insufficient validation in the Drag and Drop API in conjunction with social engineering, may have allowed
    an attacker to trick end-users into creating a shortcut to local system files. This could have been
    leveraged to execute arbitrary code. This vulnerability affects Firefox < 115. (CVE-2023-37203)

  - A website could have obscured the fullscreen notification by using an option element by introducing lag
    via an expensive computational function. This could have led to user confusion and possible spoofing
    attacks. This vulnerability affects Firefox < 115. (CVE-2023-37204)

  - The use of RTL Arabic characters in the address bar may have allowed for URL spoofing. This vulnerability
    affects Firefox < 115. (CVE-2023-37205)

  - Uploading files which contain symlinks may have allowed an attacker to trick a user into submitting
    sensitive data to a malicious website. This vulnerability affects Firefox < 115. (CVE-2023-37206)

  - A use-after-free condition existed in `NotifyOnHistoryReload` where a `LoadingSessionHistoryEntry` object
    was freed and a reference to that object remained. This resulted in a potentially exploitable condition
    when the reference to that object was later reused. This vulnerability affects Firefox < 115.
    (CVE-2023-37209)

  - A website could prevent a user from exiting full-screen mode via alert and prompt calls. This could lead
    to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 115.
    (CVE-2023-37210)

  - Memory safety bugs present in Firefox 114. 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 < 115. (CVE-2023-37212)

  - The Tungstenite crate before 0.20.1 for Rust allows remote attackers to cause a denial of service (minutes
    of CPU consumption) via an excessive length of an HTTP header in a client handshake. The length affects
    both how many times a parse is attempted (e.g., thousands of times) and the average amount of data for
    each parse attempt (e.g., millions of bytes). (CVE-2023-43669)

  - A compromised content process could have provided malicious data to `FilterNodeD2D1` resulting in an out-
    of-bounds write, leading to a potentially exploitable crash in a privileged process. *This bug only
    affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox <
    118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5168)

  - A compromised content process could have provided malicious data in a `PathRecording` resulting in an out-
    of-bounds write, leading to a potentially exploitable crash in a privileged process. This vulnerability
    affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5169)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing
    an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects
    Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3. (CVE-2023-5171)

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and
    Thunderbird < 115.3. (CVE-2023-5176)

  - It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by
    the user due to an insufficient activation-delay. This vulnerability affects Firefox < 119, Firefox ESR <
    115.4, and Thunderbird < 115.4.1. (CVE-2023-5721)

  - Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led
    to a crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
    (CVE-2023-5724)

  - A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be
    leveraged to collect sensitive user data. This vulnerability affects Firefox < 119, Firefox ESR < 115.4,
    and Thunderbird < 115.4.1. (CVE-2023-5725)

  - During garbage collection extra operations were performed on a object that should not be. This could have
    led to a potentially exploitable crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and
    Thunderbird < 115.4.1. (CVE-2023-5728)

  - Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. 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 < 119, Firefox ESR < 115.4, and
    Thunderbird < 115.4.1. (CVE-2023-5730)

  - An attacker could have created a malicious link using bidirectional characters to spoof the location in
    the address bar when visited. This vulnerability affects Firefox < 117, Firefox ESR < 115.4, and
    Thunderbird < 115.4.1. (CVE-2023-5732)
