Sometimes we get a lot of 'SMTP Long MAIL anomaly Vulnerability' critical e-mail warnings from the PaloAlto PA-500.
PA-500 is filling up our mailbox with this warnings until we block the IP-range.
Does anyone has a suggestion how to moderate this warning.
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. Could you please let me know which Application and threat version is currently installed on your PAN firewall...?
