SunOS 5.10 Remote ICMP Kernel Crash Exploit
[===========================================
SunOS 5.10 Remote ICMP Kernel Crash Exploit
===========================================
/*
SunOS 5.10 Remote ICMP Kernel Crash Exploit by kcope
Null Pointer Dereference in Kernel Space
Seems to work only if attacked in the same network segment,
maybe because of firewalls/routers in place.
This seems to be the issue described in bid 22323.
