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"
