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."

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - evolution-data-server: Response injection via STARTTLS in SMTP and POP3 (CVE-2020-14928)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
