tag_insight = "The cyrus-imapd packages contain a high-performance mail server with IMAP,
  POP3, NNTP, and Sieve support.

  It was discovered that cyrus-imapd did not flush the received commands
  buffer after switching to TLS encryption for IMAP, LMTP, NNTP, and POP3
  sessions. A man-in-the-middle attacker could use this flaw to inject
  protocol commands into a victim's TLS session initialization messages. This
  could lead to those commands being processed by cyrus-imapd, potentially
  allowing the attacker to steal the victim's mail or authentication
  credentials. (CVE-2011-1926)
  
  Users of cyrus-imapd are advised to upgrade to these updated packages,
  which contain a backported patch to correct this issue. After installing
  the update, cyrus-imapd will be restarted automatically.";
