Winamp NSV Table of Contents Parsing Integer Overflow

Winamp NSV Table of Contents Parsing Integer Overflow
Posted Dec 2, 2010
Authored by Carsten Eiram | Site secunia.com

Secunia Research has discovered a vulnerability in Winamp, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused by an integer overflow error in the "in_nsv.dll" plugin when parsing the Table of Contents. This can be exploited to cause a heap-based buffer overflow via a specially crafted NSV stream or file. Successful exploitation allows execution of arbitrary code.
