The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and SIEVE support.

Security Fix(es):

  • cyrus-imapd: privilege escalation in HTTP request (CVE-2019-18928)

  • cyrus-imapd: lmtpd component created mailboxes with administrator privileges if the “fileinto” was used, bypassing ACL checks (CVE-2019-19783)
