"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-2022:0095 advisory.

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

    CVE-2019-3890:
    It was discovered evolution-ews before 3.31.3 does not check the validity of SSL certificates. An attacker
    could abuse this flaw to get confidential information by tricking the user into connecting to a fake
    server without the user noticing the difference.

    CVE-2020-14928:
    evolution-data-server (eds) through 3.36.3 has a STARTTLS buffering issue that affects SMTP and POP3. When
    a server sends a begin TLS response, eds reads additional data and evaluates it in a TLS context, aka
    response injection.

    CVE-2020-16117:
    In GNOME evolution-data-server before 3.35.91, a malicious server can crash the mail client with a NULL
    pointer dereference by sending an invalid (e.g., minimal) CAPABILITY line on a connection attempt. This is
    related to imapx_free_capability and imapx_connect_to_server.

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.");
