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).
