{"id":"CVE-2013-0339","details":"libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue.  NOTE: it could be argued that because libxml2 already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed and each affected application would need its own CVE.","modified":"2026-01-27T04:11:33.533323Z","published":"2014-01-21T18:55:09Z","withdrawn":"2026-01-27T04:11:33.533323Z","references":[{"type":"ADVISORY","url":"http://secunia.com/advisories/52662"},{"type":"ADVISORY","url":"http://secunia.com/advisories/54172"},{"type":"ADVISORY","url":"http://secunia.com/advisories/55568"},{"type":"ADVISORY","url":"http://www.debian.org/security/2013/dsa-2652"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-1904-1"},{"type":"ADVISORY","url":"http://www.ubuntu.com/usn/USN-1904-2"},{"type":"FIX","url":"https://git.gnome.org/browse/libxml2/commit/?id=4629ee02ac649c27f9c0cf98ba017c6b5526070f"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=915149"},{"type":"WEB","url":"http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00002.html"},{"type":"WEB","url":"http://openwall.com/lists/oss-security/2013/02/21/24"},{"type":"WEB","url":"http://openwall.com/lists/oss-security/2013/02/22/3"},{"type":"WEB","url":"http://seclists.org/oss-sec/2013/q4/182"},{"type":"WEB","url":"http://seclists.org/oss-sec/2013/q4/184"},{"type":"WEB","url":"http://seclists.org/oss-sec/2013/q4/188"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2013/04/12/6"}],"schema_version":"1.7.3"}
