libmad memory corruption vulnerability

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.

Mitigation:

Upgrade to the latest version of libmad library
