Description
Run the following program on the following input:
package main
import (
"bytes"
"io/ioutil"
"os"
"golang.org/x/image/tiff"
)
func main() {
data, _ := ioutil.ReadFile(os.Args[1])
img, err := tiff.Decode(bytes.NewReader(data))
if err != nil {
return
}
var w bytes.Buffer
err = tiff.Encode(&w, img, nil)
if err != nil {
panic(err)
}
}https://drive.google.com/file/d/0B20Uwp8Hs1oCNXVZbU8zQ2ZaWmM/view?usp=sharing
It crashes with:
