Author : qflb.wu
===============


Introduction:
=============
libmad is a high-quality MPEG audio decoder capable of 24-bit output.


Affected version:
=====
0.15.1b


Vulnerability Description:
==========================
the mad_decoder_run function in decoder.c in libmad 0.15.1b can cause a denial of service(memory corruption) via a crafted mp3 file.


I found this bug when I test mpg321 0.3.2 which used the libmad library.


./mpg321 libmad_0.15.1b_memory_corruption.mp3
