# TNS Listener (Oracle RDBMS) exploit, cause Listener process crash

# While running on 11.1.0.7.0 win32, nsglvcrt() Listener function attempt
# to allocate huge memory block and copy *something* to it.

# TID=3052|(1) MSVCR71.dll!malloc (0x4222fc5) (called from 0x438631 (TNSLSNR.EXE!nsglvcrt+0x95))
# TID=3052|(1) MSVCR71.dll!malloc -> 0x2530020
# TID=3052|(0) TNSLSNR.EXE!__intel_fast_memcpy (0x2530020, 0, 0x4222fc4) (called from 0x438647 (TNSLSNR.EXE!nsglvcrt+0xab))

# (addresses are for TNS Listener 11.1.0.7.0 win32 unpatched)
# If I correct, nsglvcrt() function is involved in new service creation.
