It was found that the <code>:source!</code> command was not restricted by
|
|
|
|
|
|
the sandbox mode. If modeline was explicitly enabled, opening a specially
|
|
|
|
|
|
crafted text file in vim could result in arbitrary command execution.

<impact type="normal">
|

<p>A remote attacker could entice a user to open a specially crafted file

the privileges of the process or a Denial of Service condition.
