A remote attacker could entice a user to open a specially crafted XML
|
||
|
|
document with an application using libxml2, possibly resulting in a
|
||
|
|
high CPU consumption. Note that this vulnerability could also be
|
||
|
|
triggered without user interaction by an automated system processing
|
||
|
|
XML content.

<workaround>
|

<p>
|
||
|

There is no known workaround at this time.
