<background>
|
||
<p>Vim is an efficient, highly configurable improved version of the classic
|
||
‘vi’ text editor. gVim is the GUI version of Vim.
|
||
</p>
|
||
</background>
|
||
<description>
|
||
<p>Vim and gVim do not properly validate values for the ‘filetype’,
|
||
‘syntax’, and ‘keymap’ options.
|
||
</p>
|
||
</description>
|
||
<impact type="normal">
|
||
<p>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.
|
||
</p>
|
||
</impact>
|
||
<workaround>
|
||
<p>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.
|
||
</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All Vim users should upgrade to the latest version:</p>
|
||
|
||
<code>
|
||
# emerge --sync
|
||
# emerge --ask --oneshot --verbose ">=app-editors/vim-8.0.0106"
|
||
</code>
|
||
|
||
<p>All gVim users should upgrade to the latest version:</p>
|
||
|
||
<code>
|
||
# emerge --sync
|
||
# emerge --ask --oneshot --verbose ">=app-editors/gvim-8.0.0106"
|
||
</code>
