"The version of MariaDB installed on the remote host is prior to 12.3.3, 13.0.2. It is, therefore, affected by a
vulnerability as referenced in the GHSA-mv8g-9f7q-hprm advisory.

  - ### Impact  When a large number of SYS_REFCURSOR's are opened and then one of them is fetched, it is
    possible to trigger a use-after-free condition. It could be used in a multi-vulnerability exploitation
    chain (combined with, for example, [this vulnerability](GHSA-p7v9-24h4-mch8) for a full remote code
    execution exploitation.    ### Patches  Fixed in 12.3.3, 13.0.2.    ### Workarounds  There is no
    workaround. Users are advised to upgrade immediately.    ### References
