It was discovered that the Dovecot email server is vulnerable to a denial of service attack. 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 .
