[Snort-users] "SHELLCODE x86 NOOP" from presumably non dangerous addresses

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.
