  - A vulnerability was found in zstd v1.4.10, where an attacker can supply empty string as an argument to the
    command line tool to cause buffer overrun. (CVE-2022-4899)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 8.0.32 and prior. Easily exploitable vulnerability allows high privileged attacker with
    network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability
    can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL
    Server. (CVE-2023-21911, CVE-2023-22104)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported
    versions that are affected are 8.0.32 and prior. Easily exploitable vulnerability allows high privileged
    attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this
    vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete
    DOS) of MySQL Server. (CVE-2023-21920, CVE-2023-21935, CVE-2023-21945, CVE-2023-21976, CVE-2023-21977,
    CVE-2023-21982)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DDL). Supported versions
    that are affected are 8.0.32 and prior. Easily exploitable vulnerability allows high privileged attacker
    with network access via multiple protocols to compromise MySQL Server. Successful attacks of this
    vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete
    DOS) of MySQL Server. (CVE-2023-21919, CVE-2023-21933)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Components Services).
    Supported versions that are affected are 8.0.32 and prior. Difficult to exploit vulnerability allows high
    privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful
    attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable
    crash (complete DOS) of MySQL Server. (CVE-2023-21940, CVE-2023-21947)
