CVE-2018-14404 libxml2: NULL pointer dereference in xmlXPathCompOpEval() function in xpath.c
libxml2 is vulnerable to a NULL pointer dereference in the xpath.c:xmlXPathCompOpEval() function due to missing checks for NULL in XPATH_OP_AND and XPATH_OP_OR switch cases. An attacker could exploit this via crafted xpath expressions to cause a denial of service.
