A flaw was found in libxml2 2.9.8. The xzdecomp function in xzlib.c, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMAMEMLIMITERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035.

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 XPATHOPAND or XPATHOPOR 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.
