FEDORA-2018-52d79f4f36

security update in Fedora 27 for dovecot

Status: stable a year ago
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
  process.
