Fedora 29: FEDORA-2019-f0435555ac Critical: cyrus-imapd Buffer Overrun

The Cyrus IMAP (Internet Message Access Protocol) server provides access to

personal mail, system-wide bulletin boards, news-feeds, calendar and contacts

through the IMAP, JMAP, NNTP, CalDAV and CardDAV protocols. The Cyrus IMAP

server is a scalable enterprise groupware system designed for use from small to

large enterprise environments using technologies based on well-established Open

Standards.

A full Cyrus IMAP implementation allows a seamless mail and bulletin board

environment to be set up across one or more nodes. It differs from other IMAP

server implementations in that it is run on sealed nodes, where users are not

normally permitted to log in. The mailbox database is stored in parts of the

filesystem that are private to the Cyrus IMAP system. All user access to mail

is through software using the IMAP, IMAPS, JMAP, POP3, POP3S, KPOP, CalDAV

and/or CardDAV protocols.

The private mailbox database design gives the Cyrus IMAP server large

advantages in efficiency, scalability, and administratability. Multiple

concurrent read/write connections to the same mailbox are permitted. The server

supports access control lists on mailboxes and storage quotas on mailbox

hierarchies.
