|
|
Randy Smith, Christian Estan and Somesh Jha discovered that the rule
|
|
matching algorithm of Snort can be exploited in a way known as a
|
|
"backtracking attack" to perform numerous time-consuming operations.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could send specially crafted network packets, which
|
|
would result in the cessation of the detections and the consumption of
|
|
the CPU resources.
|
|
</p>
|

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