When the "dict" passdb and userdb are used for user authentication, the username sent by the IMAP/POP3 client is sent through var_expand() to perform %variable expansion. Sending specially crafted %variable fields could result in excessive memory usage causing the process to crash (and restart). For the stable distribution (jessie), this problem has been fixed in version 1:2.2.13-12~deb8u2. We recommend that you upgrade your dovecot packages.
