Oracle Internet Directory 10.1.4 preauthentication Denial Of ServiceNOTES: 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_64Vulnerability found by Joxean Koret (joxeankoret [ at ] yahoo DOT es)Fixed: Oracle Critical Patch Update July 2008
