我用Fuzzing-ImageMagick 搞了两天也没搞出个crash。

whiteHat001 commented 7 years ago

是的,我用别人以前的poc跑的,很快就出来了

a7903 commented 7 years ago

用别人的poc 直接alf-fuzz fuzz的吗?

whiteHat001 commented 7 years ago

嗯,别人以前的poc,我收集起来fuzz的

a7903 commented 7 years ago

以前的poc,那不是都已经把漏洞修复了嘛,还能继续用?

whiteHat001 commented 7 years ago

当然可以跑啊,跟版本没关系,afl会根据以前的poc来产生另外的东西去跑,

好的我再去试试,多谢大佬了,有问题在回来问你。
