The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2023:0148 advisory.

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

      CVE-2020-18032:
      A flaw was found in graphviz. A wrong assumption in record_init function leads to an off-by-one write in     parse_reclbl function, allowing an attacker who can provide graph input to potentially execute code when     the label of a node is invalid and shorter than two characters. The highest threat from this vulnerability     is to data confidentiality and integrity as well as system availability.
