PHPExcel vulnerable to XXE attacks through libxml
PHPExcel before 1.8.0, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, does not disable external entity loading in libxml, which allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.
