'Name' => 'Csound hetro File Handling Stack Buffer Overflow',
|
|
'Description' => %q{
|
|
This module exploits a buffer overflow in Csound before 5.16.6.
|
|
The overflow occurs when trying to import a malicious hetro file
|
|
from tabular format.
|
|
In order to achieve exploitation the user should import the malicious
|
|
file through csound with a command like "csound -U het_import msf.csd file.het".
|
|
This exploit doesn't work if the "het_import" command is used directly
|
|
to convert the file.
