Hi,
I was playing around with the ICMP error messages DOS attack (I found an exploit on securityfocus.org bid 13214), and I noticed the following work around:
when I add the following rule to iptables, the linux server (Kernel 2.4.29-grsec) is no longer vulnerable to the DOS:
iptables -I INPUT 1 -p icmp -j DROP
I am interested in knowing if this work around makes any sense. Please keep me informed about this vulnerability.
Thank you, Alok.
