A flaw was found in libxml2 2.9.8. The xz_decomp 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 LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint (CVE-2018-9251, CVE-2018-14567). A null pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 when parsing invalid XPath expression. Applications processing untrusted XSL format inputs with the use of libxml2 library may be vulnerable to denial of service attack due to crash of the application (CVE-2018-14404). The libxml2 package has been updated to version 2.9.9 to fix these issues and other bugs. The perl-XML-LibXML package has been rebuilt against the updated libxml2.
