NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-static package and not the libxml2-static package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application.
