  - When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to
    ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle
    previously was used to issue a `PUT` request which used that callback. This flaw may surprise the
    application and cause it to misbehave and either send off the wrong data or use memory after free or
    similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is
    changed from a PUT to a POST. (CVE-2022-32221)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions
    that are affected are 8.0.31 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-2023-21836)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: PS). Supported versions that
    are affected are 5.7.40 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-2023-21840)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported
    versions that are affected are 8.0.31 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-2023-21863, CVE-2023-21867, CVE-2023-21870, CVE-2023-21873, CVE-2023-21876,

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported
    versions that are affected are 8.0.31 and prior. Easily exploitable vulnerability allows low 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-2023-21868)

  - Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 8.0.31 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 as well as unauthorized update, insert or delete access to some of MySQL Server accessible data.
