Rule:--Sid:2330--Summary:This event is generated when a remote user sends an overly long string to an IMAP server via the command AUTH. This may indicate an attempt to exploit a buffer overflow condition.--Impact:Serious. Possible remote execution of arbitrary code, which may lead toa remote root compromise.--Detailed Information:When a large amount of data is sent to a vulnerable IMAP server in the AUTHENTICATE command, a buffer overflow condition may occur. This can allow the attacker to execute arbitrary code, which may allow the attacker to gain root access to the compromised server.--Affected Systems:	IMAP servers--Attack Scenarios:An attacker can send a sufficiently long AUTHENTICATE command to the IMAP server, creating a buffer overflow condition. This can then allow the attacker to execute code of their choosing and possibly gain root access to the compromised server.--Ease of Attack:Simple. Exploits exist.--False Positives:None known.--False Negatives:None known.--Corrective Action:Apply the appropriate patches for your operating system.Check the host for signs of compromise.--Contributors:Sourcefire Vulnerability Research TeamBrian Caswell <bmc@sourcefire.com>Nigel Houghton <nigel.houghton@sourcefire.com>--Additional References:--
