   An update that fixes four vulnerabilities is now available.

Description:

   This update for libxml2 fixes the following security issues:

   - CVE-2018-9251: The xz_decomp function allowed remote attackers to cause
     a denial of service (infinite loop) via a crafted XML file that triggers
     LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint (bsc#1088279).
   - CVE-2018-14567: Prevent denial of service (infinite loop) via a crafted
     XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint
     (bsc#1105166).
   - CVE-2018-14404: Prevent NULL pointer dereference in the
     xmlXPathCompOpEval() function when parsing an invalid XPath expression
     in the XPATH_OP_AND or XPATH_OP_OR case leading to a denial of service
     attack (bsc#1102046).
   - CVE-2017-18258: The xz_head function allowed remote attackers to cause a
     denial of service (memory consumption) via a crafted LZMA file, because
     the decoder functionality did not restrict memory usage to what is
     required for a legitimate file (bsc#1088601).
