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-2022:0102 advisory.

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

    CVE-2019-18934:
    Unbound 1.6.4 through 1.9.4 contain a vulnerability in the ipsec module that can cause shell code     execution after receiving a specially crafted answer. This issue can only be triggered if unbound was     compiled with `--enable-ipsecmod` support, and ipsecmod is enabled and used in the configuration.

    CVE-2020-12662:
    Unbound before 1.10.1 has Insufficient Control of Network Message Volume, aka an NXNSAttack issue. This     is triggered by random subdomains in the NSDNAME in NS records.

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.
