lxml is vulnerable to denial of service attacks. The vulnerability exists through a null pointer dereference in _appendStartNsEvents function of iterparse.pxi when incorrect parser input occurs together with usages of iterwalk() on trees generated by the same parser which allows an attacker to cause an application crash.
