Synopsis

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

2. Impact Information

Background

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

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.

3. Resolution Information
