From (http://jeyoshiki.yculblog.com/post-165043.html) As we all know, Yahoo Mail does not provide the pop access service, So Yahoo Mail can only receive emails online login, rather than using Outlook or Foxmail and other software. However, Yahoo's mailbox actually has a way to activate the pop access service. As lo

, we use the custom client to log in based on the user name and password, and then send the message using the SMTP service. However, the newly registered 163 messages are not turned on by default for Client authorization verification (default on for custom mailbox master clients),Therefore the login is always rejected, and authentication does not have permissions. The solution is to enter 163 mailbox, enter

to remotely execute arbitrary code in the SMTP server by constructing a sequence of BDAT commands. The researchers also published the POC exploit code written in Python, where anyone can execute code in a vulnerable Exim server.The second vulnerability is a DOS vulnerability, cve-2017-16944, which can cause a remote attacker to suspend the Exim server by forcing it to run indefinitely without crashing in the case of a connection shutdown.
