Buffer overflow in proxyd for Cyrus IMAP Server 2.2.9 and earlier, with the imapmagicplus option enabled, may allow remote attackers to execute arbitrary code, a different vulnerability than CVE-2004-1011.

The remote host is missing Security Update 2005-003. This security update contains security fixes for the following applications :

  - AFP Server
  - Bluetooth Setup Assistant
  - Core Foundation
  - Cyrus IMAP
  - Cyrus SASL
  - Folder Permissions
  - Mailman
  - Safari

These programs have multiple vulnerabilities which may allow a remote attacker to execute arbitrary code.

A number of vulnerabilities in the Cyrus-IMAP server were found by Stefan Esser. Due to insufficient checking within the argument parser of the 'partial' and 'fetch' commands, a buffer overflow could be exploited to execute arbitrary attacker-supplied code. Another exploitable buffer overflow could be triggered in situations when memory allocation files.

The provided packages have been patched to prevent these problems.

The remote host is affected by the vulnerability described in GLSA-200411-34 (Cyrus IMAP Server: Multiple remote vulnerabilities)

    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.

According to its banner, the remote Cyrus IMAPD server is vulnerable to one pre-authentication buffer overflow, as well as three post- authentication buffer overflows. A remote attacker could exploit these issues to crash the server, or possibly execute arbitrary code.
