"""
Oracle Internet Directory 10.1.4 preauthentication Denial Of Service
NOTES: Under 32 bits platforms it crashes immediately. Under 64 bits it may take even hours.
Sometimes you need 2 shoots to crash OID completely. The server "commonly" tolerates one
shoot, but even when you only send one packet it will crash.
Tested: Win2000 x86, WinXP x86, Win2003 X86_64
Vulnerability found by Joxean Koret (joxeankoret [ at ] yahoo DOT es)
Fixed: Oracle Critical Patch Update July 2008
CVEID: CVE-2008-2595
