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).

The remote Fedora 40 host has packages installed that are affected by a vulnerability as referenced in the FEDORA-2023-f81c1ab1e6 advisory.

    - Update the axum crate to version 0.6.20.
    - Update the tokio-tungstenite crate to version 0.20.1.
    - Update the tungstenite crate to version 0.20.1.
    - Port warp from tungstenite v0.18 to v0.20.

    Version 0.20.1 of the tungstenite crate includes a fix for CVE-2023-43669. No dependent applications need     to be rebuilt since none of them use the WebSocket functionality of axum or warp.

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)
