The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2021:2605-1 advisory.

  • 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). (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 and 8.0.23 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). (CVE-2021-2166)

  • A remote code execution issue was discovered in MariaDB 10.2 before 10.2.37, 10.3 before 10.3.28, 10.4 before 10.4.18, and 10.5 before 10.5.9; Percona Server through 2021-03-03; and the wsrep patch through 2021-03-03 for MySQL. An untrusted search path leads to eval injection, in which a database SUPER user can execute OS commands after modifying wsrep_provider and wsrep_notify_cmd. NOTE: this does not affect an Oracle product. (CVE-2021-27928)

Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
