  Overview: This host has Dovecot ACL Plugin installed and is prone to
  multiple security bypass vulnerabilities.

  Vulnerability Insight:
  The flaws are due to,
  - the ACL plugin interprets negative access rights as positive access rights,
    potentially giving an unprivileged user access to restricted resources.
  - an error in the ACL plugin when imposing mailbox creation restrictions to
    to create parent/child/child mailboxes.

  Impact: Successful attack could allow malicious people to bypass certain
  security restrictions or manipulate certain data.

  Impact Level: Application

  Affected Software/OS:
  Dovecot versions prior to 1.1.4 on Linux

  Fix: Upgrade to Dovecot version 1.1.4
