For starters take a look here:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=111681

The odd thing is that it looks like the affected systems should all be patched 
by now and the only mention of it is on RHEL systems.

This would work to fix your situation I think.

Add to /etc/sysctl.conf the following line:
net.ipv4.icmp_ignore_bogus_error_responses=1
