What is CVE-2020-16118?

In GNOME Balsa prior to version 2.6.0, a vulnerability exists that allows a malicious server operator or a man-in-the-middle attacker to exploit the application. By sending a specially crafted PREAUTH response during the IMAP connection process, this vulnerability can lead to a NULL pointer dereference, which subsequently causes the client to crash. This presents a significant risk to user data and security during email communication.
