The remote CentOS Linux 8 host has packages installed that are affected by a vulnerability as referenced in the CESA-2021:1752 advisory.

  - evolution-data-server: NULL pointer dereference related to imapx_free_capability and     imapx_connect_to_server (CVE-2020-16117)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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)

  - 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.(CVE-2020-16117)
