我试图升级bash，所以它不是脆弱的。
我尝试了Debian的Sources List Generator。 但是libtinfo5阻止我升级bash。 我找不到libtinfo5旧版本（由于源代码列表问题），看是否可以安装它。

wget http://snapshot.debian.org/archive/debian-archive/20160313T130328Z/debian/pool/main/b/bash/bash_4.1-3%2Bdeb6u2_amd64.deb （假设amd64是你的架构） dpkg -i bash_4.1-3+deb6u2_amd64.deb （以root用户身份通过sudo ） 认真：升级这个系统，或者如果离线。
