"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0632 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2023-52971:
    MariaDB Server 10.10 through 10.11.* and 11.0 through 11.4.* crashes in JOIN::fix_all_splittings_in_plan.

    CVE-2023-52970:
    MariaDB Server 10.4 through 10.5.*, 10.6 through 10.6.*, 10.7 through 10.11.*, 11.0 through 11.0.*, and
    11.1 through 11.4.* crashes in Item_direct_view_ref::derived_field_transformer_for_where.

    CVE-2023-52969:
    MariaDB Server 10.4 through 10.5.*, 10.6 through 10.6.*, 10.7 through 10.11.*, and 11.0 through 11.0.* can
    sometimes crash with an empty backtrace log. This may be related to make_aggr_tables_info and
    optimize_stage2.

    CVE-2023-52968:
    MariaDB Server 10.4 before 10.4.33, 10.5 before 10.5.24, 10.6 before 10.6.17, 10.7 through 10.11 before
    10.11.7, 11.0 before 11.0.5, and 11.1 before 11.1.4 calls fix_fields_if_needed under mysql_derived_prepare
    when derived is not yet prepared, leading to a find_field_in_table crash.
