"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-2023:0199 advisory.

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

      CVE-2023-2454:
      schema_element defeats protective search_path changes; It was found that certain database calls in
    PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary
    code.

      CVE-2023-2455:
      Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect
    policies to be applied in certain cases where role-specific policies are used and a given query is planned
    under one role and then executed under other roles. This scenario can happen under security definer
    functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs.
    Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications.
    This affects only databases that have used CREATE POLICY to define a row security policy.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
