The description says "This signature detects an anomaly in SMTP protocol. It would trigger when anoverlong mail command argument is passed to MAIL command."

Can anyone elaborate on this definition or know where I can access more detailed information about this threat ID?

Thanks !!!!!

Hello Craigmueller,

This is triggered when an argument to a MAIL command to an SMTP server is overly long (304 bytes). This triggers a buffer overflow leading to a DOS and/or possible remote code execution
