"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2011-212:01 advisory.

    Dovecot is an IMAP server for Linux/UNIX-like systems, written with security primarily in mind.  It also
    contains a small POP3 server.  It supports mail in either of maildir or mbox formats.
    The SQL drivers and authentication plug-ins are in their subpackages.
    Security issues fixed with this release:
    CVE-2010-3707
    plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL
    entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to
    replace the permissions granted by another ACL entry, in certain circumstances involving more specific
    entries that occur after less specific entries, which allows remote authenticated users to bypass intended
    access restrictions via a request to read or modify a mailbox.
    CVE-2010-3780
    Dovecot 1.2.x before 1.2.15 allows remote authenticated users to cause a denial of service (master process
    outage) by simultaneously disconnecting many (1) IMAP or (2) POP3 sessions.
    Enhancements:
     - Upgraded to version 2.0.9. Refer to the /usr/share/doc/dovecot-2.0.9/ChangeLog file after installation
    for a full list of bug fixes and improvements.
