Fix vim input Validation Vulnerability

CentOS 6, vim 7, cve-2016-1248

Aliyun has advertised Vim 7 's input verification vulnerability, a security vulnerability in the previous version of Vim patch 8.0.0056, which stems from the program's failure to properly verify the value of the ' filetype ', ' syntax ', and ' keymap ' options that could allow an attacker to execute arbitrary code.

Log on to the server, uninstall the original vim, add the source, and then update to verify if it is installed.

Yum Remove vim-*-y
wget-p/etc/yum.repos.d/  https://copr.fedorainfracloud.org/coprs/mcepl/vim8/repo/ Epel-7/mcepl-vim8-epel-7.repo
yum-y Install vim-enhanced sudo
rpm-qa vim
