security update in Fedora 26 for dovecot

Status: obsolete
dovecot updated to 2.2.34, pigeonhole updated to 0.4.22
fixes CVE-2017-15130: TLS SNI config lookups may lead to excessive
  memory usage, causing imap-login/pop3-login VSZ limit to be reached
  and the process restarted. This happens only if Dovecot config has
  local_name { } or local { } configuration blocks and attacker uses
  randomly generated SNI servernames.
fixes CVE-2017-14461: Parsing invalid email addresses may cause a crash or
  leak memory contents to attacker. For example, these memory contents
  might contain parts of an email from another user if the same imap
  process is reused for multiple users.
fixes CVE-2017-15132: Aborted SASL authentication leaks memory in login

  • doveadm: Fix crash in proxying (or dsync replication) if remote is running older than v2.2.33
  • auth: Fix memory leak in %{ldap_dn}
  • dict-sql: Fix data types to work correctly with Cassandra
