Synopsis |
16 |
======== |
17 |
|
18 |
A vulnerability has been found in Vim and gVim concerning how certain |
19 |
modeline options are treated. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Vim is an efficient, highly configurable improved version of the |
25 |
classic ‘vi’ text editor. gVim is the GUI version of Vim. |
26 |
|

Description |
39 |
=========== |
40 |
|
41 |
It was found that the `:source!` command was not restricted by the |
42 |
sandbox mode. If modeline was explicitly enabled, opening a specially |
43 |
crafted text file in vim could result in arbitrary command execution. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker could entice a user to open a specially crafted file |
49 |
using Vim or gVim, possibly resulting in execution of arbitrary code |
50 |
with the privileges of the process or a Denial of Service condition. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All Vim users should upgrade to the latest version: |
61 |
|
62 |
# emerge --sync |
63 |
# emerge --ask --oneshot --verbose ">=app-editors/vim-8.1.1486" |
64 |
|
65 |
All gVim users should upgrade to the latest version: |
66 |
|
67 |
# emerge --sync |
68 |
# emerge --ask --oneshot --verbose ">=app-editors/gvim-8.1.1486" |
