  - VP9 in libvpx before 1.13.1 mishandles widths, leading to a crash related to encoding. (CVE-2023-44488)

  - 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.
