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

2.  Impact Information


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


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).


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

3.  Resolution Information


There is no known workaround at this time.


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

Code Listing 3.1: Resolution

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