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." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "name": "52662", "refsource": "SECUNIA", "url": "http://secunia.com/advisories/52662" }, { "name": "SUSE-SU-2013:1627", "refsource": "SUSE", "url": "http://lists.opensuse.org/opensuse-security-announce/2013-11/msg00002.html" }, { "name": "[oss-security] 20130221 CVE Guidance for Libraries and Resource-Consumption DoS", "refsource": "MLIST", "url": "http://openwall.com/lists/oss-security/2013/02/21/24" }, { "name": "[oss-security] 20130221 CVEs for libxml2 and expat internal and external XML entity expansion", "refsource": "MLIST", "url": "http://openwall.com/lists/oss-security/2013/02/22/3" }, { "name": "[oss-security] 20131029 Re: CVE Request: libxml2 external parsed entities issue", "refsource": "MLIST", "url": "http://seclists.org/oss-sec/2013/q4/188" }, { "name": "[oss-security] 20131029 Re: CVE Request: libxml2 external parsed entities issue", "refsource": "MLIST", "url": "http://seclists.org/oss-sec/2013/q4/184" }, { "name": "[oss-security] 20131028 Re: CVE Request: libxml2 external parsed entities issue", "refsource": "MLIST", "url": "http://seclists.org/oss-sec/2013/q4/182" }, { "name": "USN-1904-2", "refsource": "UBUNTU", "url": "http://www.ubuntu.com/usn/USN-1904-2" }, { "name": "USN-1904-1", "refsource": "UBUNTU", "url": "http://www.ubuntu.com/usn/USN-1904-1" }, { "name": "DSA-2652", "refsource": "DEBIAN", "url": "http://www.debian.org/security/2013/dsa-2652" }, { "name": "https://bugzilla.redhat.com/show_bug.cgi?id=915149", "refsource": "MISC", "url": "https://bugzilla.redhat.com/show_bug.cgi?id=915149" }, { "name": "54172", "refsource": "SECUNIA", "url": "http://secunia.com/advisories/54172" }, { "name": "55568", "refsource": "SECUNIA", "url": "http://secunia.com/advisories/55568" }, { "name": "https://git.gnome.org/browse/libxml2/commit/?id=4629ee02ac649c27f9c0cf98ba017c6b5526070f", "refsource": "MISC", "url": "https://git.gnome.org/browse/libxml2/commit/?id=4629ee02ac649c27f9c0cf98ba017c6b5526070f" }, { "name": "[oss-security] 20130412 Re-evaluating expat/libxml2 CVE assignments", "refsource": "MLIST", "url": "http://www.openwall.com/lists/oss-security/2013/04/12/6" } ] } }
