CVE-2015-8806 [HIGH] libxml2 vulnerabilities
Title: libxml2 vulnerabilities
Summary: Several security issues were fixed in libxml2.
It was discovered that libxml2 incorrectly handled certain malformed
documents. If a user or automated system were tricked into opening a
specially crafted document, an attacker could possibly cause libxml2 to
crash, resulting in a denial of service. (CVE-2015-8806, CVE-2016-2073,
CVE-2016-3627, CVE-2016-3705, CVE-2016-4447)
It was discovered that libxml2 incorrectly handled certain malformed
documents. If a user or automated system were tricked into opening a
specially crafted document, an attacker could cause libxml2 to crash,
resulting in a denial of service, or possibly execute arbitrary code.
