Synopsis
========
A vulnerability has been found in Vim and gVim concerning how certain
modeline options are treated.
Background
==========
Vim is an efficient, highly configurable improved version of the
classic 'vi' text editor. gVim is the GUI version of Vim.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-editors/vim < 8.0.0106 >= 8.0.0106
2 app-editors/gvim < 8.0.0106 >= 8.0.0106
-------------------------------------------------------------------
2 affected packages
Description
===========
Vim and gVim do not properly validate values for the 'filetype',
'syntax', and 'keymap' options.
Impact
======
A remote attacker could entice a user to open a specially crafted file
using Vim/gVim with certain modeline options enabled possibly resulting
in execution of arbitrary code with the privileges of the process.
Workaround
==========
Disabling modeline support in .vimrc by adding "set nomodeline" will
prevent exploitation of this flaw. By default, modeline is enabled for
ordinary users but disabled for root.
Resolution
==========
All Vim users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/vim-8.0.0106"
All gVim users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-editors/gvim-8.0.0106"
