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"
