Oracle Database is prone to a remote memory-corruption vulnerability in Listener.

The vulnerability can be exploited over the 'Oracle Net' protocol. An attacker does not require privileges to exploit this vulnerability.

This vulnerability affects the following supported versions:

9.2.0.8, 9.2.0.8DV, 10.1.0.5, 10.2.0.4, 11.1.0.7

# 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.

# Successfully crashed:

#Oracle RDBMS 11.1.0.6.0 win32 with CPUapr2009 applied

#Oracle RDBMS 11.1.0.7.0 win32 with CPUapr2009 applied

#Oracle RDBMS 10.2.0.4 win32 with CPUapr2009 applied

#Oracle RDBMS 10.2.0.2 Linux x86

# Not crashed:

#Oracle RDBMS 11.2 Linux x86

# Vulnerability discovered by Dennis Yurichev <dennis@conus.info>

# Fixed in CPUjan2010 as CVE-2010-0071 (CVSS 10.0):

# http://www.oracle.com/technology/deploy/security/critical-patch-updates/cpujan2010.html
