panic: runtime error: index out of range in maindata.readHuffman #22
Description
Hello.
I found a index out of range bug in go-mp3.
Please confirm.
Thanks.
reproduce code:
package mp3
import (
"bytes"
"testing"
)
type bytesReadCloser struct {
*bytes.Reader
}
func (b *bytesReadCloser) Close() error {
return nil
}
func TestFuzzingIssue3(t *testing.T) {
inputs := []string{
"\xff\xfa%00000000000000000" +
"000000000000s0000000" +
"00000000000000000000" +
"00000000000000000000" +
"00000000000000000000" +
"00000000000000000000",
}
for _, input := range inputs {
b := &bytesReadCloser{bytes.NewReader([]byte(input))}
_, _ = NewDecoder(b)
}
}
