A flaw was discovered in the CalDAV feature in httpd of the Cyrus IMAP server, leading to denial of service or potentially the execution of arbitrary code via a crafted HTTP PUT operation for an event with a long iCalendar property name.

For the stable distribution (stretch), this problem has been fixed in version 2.5.10-3+deb9u1.

We recommend that you upgrade your cyrus-imapd packages.
