  A denial of service flaw was found in the way Dovecot handled NULL

  headers could cause the Dovecot child process handling the target user's
  connection to crash, blocking them from downloading the message
  successfully and possibly leading to the corruption of their mailbox.
  (CVE-2011-1929)

  Users of dovecot are advised to upgrade to these updated packages, which
  contain a backported patch to resolve this issue. After installing the
  updated packages, the dovecot service will be restarted automatically.");
