    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2021-2154:
    Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: DML). Supported versions
    that are affected are 5.7.33 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. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).

    Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 5.7.34 and prior and 8.0.25 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. CVSS 3.1 Base Score 4.4 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H).

    CVE-2021-2389:
    Vulnerability in the MySQL Server product of Oracle MySQL (component: InnoDB). Supported versions that are
    affected are 5.7.34 and prior and 8.0.25 and prior. Difficult to exploit vulnerability allows
    unauthenticated 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. CVSS 3.1 Base Score 5.9 (Availability impacts). CVSS Vector:
    (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).
