<description>
|
||
<p>A crafted file could cause a buffer overflow in the ‘dev_map_read’
|
||
function because the device and devno arrays are too small.

<impact type="normal">
|
||
<p>A remote attacker could entice a user to open a specially crafted file
|
||
using blktrace, possibly resulting in execution of arbitrary code with
|
||
the privileges of the process or a Denial of Service condition.

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