The results of an attack on a vulnerable XML library can be fairly dramatic.
With just a few hundred Bytes of XML data an attacker can occupy several
Gigabytes of memory within seconds. An attacker can also keep CPUs busy for a
long time with a small to medium size request. Under some circumstances it is
even possible to access local files on your server, to circumvent a firewall,
or to abuse services to rebound attacks to third parties. This library allows
for XML to be parsed in a manner that avoids these pitfalls.
