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"
