The remote host is missing an update for the Debian 'cyrus-imapd' package(s) announced via the DSA-4590-1 advisory. It was discovered that the lmtpd component of the Cyrus IMAP server created mailboxes with administrator privileges if the fileinto was used, bypassing ACL checks. For the oldstable distribution (stretch), this problem has been fixed in version 2.5.10-3+deb9u2. For the stable distribution (buster), this problem has been fixed in version 3.0.8-6+deb10u3. We recommend that you upgrade your cyrus-imapd packages
