"SHELLCODE x86 NOOP" from presumably non dangerous addresses

Hi, I'm receiving several "SHELLCODE x86 NOOP" alerts from addresses like "law2-www.hotmail.com" and another one in akamai (presumably, one of those used in ad banners: a62-41-13-32.deploy.akamaitechnologies.com). Is there a non-paranoid explanation of what could be happening? I think that maybe the transmission of some gif/jpg or some attach could trigger the alert, but I'm not very sure. BTW, we're using OpenSSH from a linux box to the linux sensor that hosts snort, and the alert "EXPLOIT ssh CRC32 overflow filler" is triggered. Any hint of what could be this? Just an over-sensitive rule? Thanks in advance. -- Roberto Suarez Soto Alfa21 Outsourcing robe () alfa21 com http://www.alfa21.com _______________________________________________ Snort-users mailing list Snort-users () lists sourceforge net Go to this URL to change user options or unsubscribe: https://lists.sourceforge.net/lists/listinfo/snort-users Snort-users list archive: http://www.geocrawler.com/redir-sf.php3?list=snort-users
