  - 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)
