ArchLinux: 201702-12: gvim: arbitrary code execution
Summary
It was found that vim does not properly validate values for tree length when handling a spell file, which may result in an integer overflow at a memory allocation site and a resultant buffer overflow.
Resolution
Upgrade to 8.0.0322-1.
# pacman -Syu "gvim>=8.0.0322-1"
The problem has been fixed upstream in version 8.0.0322.
