------------------------------------------------------------------------------- - Fedora Update Notification FEDORA-2020-b60344c987 2020-05-28 01:59:14.571867 ------------------------------------------------------------------------------- -
Name : dovecot Product : Fedora 31 Version : 2.3.10.1 Release : 1.fc31 URL : http://www.dovecot.org/ Summary : Secure imap and pop3 server Description : Dovecot is an IMAP server for Linux/UNIX-like systems, written with security primarily in mind. It also contains a small POP3 server. It supports mail in either of maildir or mbox formats.
The SQL drivers and authentication plug-ins are in their subpackages.
------------------------------------------------------------------------------- - Update Information:
- CVE-2020-10957: lmtp/submission: A client can crash the server by sending a NOOP command with an invalid string parameter. This occurs particularly for a parameter that doesn't start with a double quote. This applies to all SMTP services, including submission-login, which makes it possible to crash the submission service without authentication. - CVE-2020-10958: lmtp/submission: Sending many invalid or unknown commands can cause the server to access freed memory, which can lead to a server crash. This happens when the server closes the connection with a "421 Too many invalid commands" error. The bad command limit depends on the service (lmtp or submission) and varies between 10 to 20 bad commands. - CVE-2020-10967: lmtp/submission: Issuing the RCPT command with an address that has the empty quoted string as local-part causes the lmtp service to crash. ------------------------------------------------------------------------------- - ChangeLog:
