<impact type="high">
|
||
|
<p>in the Perl background extension, when an attacker can
|
||
|
control the data written to the user's terminal and certain options are set.
|
||
|
|
||
|
The "background" extension is automatically loaded if certain X resources are set such as 'transparent' (see the full list at the top of src/perl/background[1]). So it is possible to be using this extension without realising it.</p>

<p>There is no known workaround at this time.</p>

<resolution>
