Segmentation Fault caused by malformed audio files.

[tomatitofrito]

Hi

After having done some fuzz testing with zzuf I saw that feeding Soundconverter with malformed mp3 files crashes the program due to a segmentation fault. These were the commands used for the test:

This first command was used to generate hundreds of malformed .mp3 files:

for i in {10..15}; do for f in *.mp3;do zzuf -r 0.04 -s $i < "$f" > "$i-$f"; done; done

And this second command was used to feed soundconverter with the malformed files.

LC_ALL=C; LANG=C; for f in *.mp3; do timeout 3 soundconverter -b -m audio/x-wav -s .wav "$f"; done &>fuzzing_soundconverter.log

You can find more information explaining how to use zzuf through the following sources:

I hope you find this information useful.

Kind regards.
