    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.

According to the versions of the evolution-data-server packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - 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-2020-14928)

  - addressbook/backends/ldap/e-book-backend-ldap.c in     Evolution-Data-Server in GNOME Evolution through 3.29.2     might allow attackers to trigger a Buffer Overflow via     a long query that is processed by the strcat function.
    NOTE: the software maintainer disputes this because     'the code had computed the required string length     first, and then allocated a large-enough buffer on the     heap.'(CVE-2018-12422)
