    Synopsis
    ========

    The Cyrus IMAP Server contains multiple vulnerabilities which could
    lead to remote execution of arbitrary code.

    Background
    ==========

    The Cyrus IMAP Server is an efficient, highly-scalable IMAP e-mail
    server.

    Affected packages
    =================

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-mail/cyrus-imapd < 2.2.10 >= 2.2.10

    Description
    ===========

    Multiple vulnerabilities have been discovered in the argument parsers
    of the 'partial' and 'fetch' commands of the Cyrus IMAP Server
    (CAN-2004-1012, CAN-2004-1013). There are also buffer overflows in the
    'imap magic plus' code that are vulnerable to exploitation as well
    (CAN-2004-1011, CAN-2004-1015).

    Impact
    ======

    An attacker can exploit these vulnerabilities to execute arbitrary code
    with the rights of the user running the Cyrus IMAP Server.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Cyrus-IMAP Server users should upgrade to the latest version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-mail/cyrus-imapd-2.2.10"
