There is DTDs support this includes parsing and\n validation even with complex DtDs, either at parse time\n or later once the document has been modified. The\n output can be a simple SAX stream or and in-memory DOM\n like representations. In this case one can use the\n built-in XPath and XPointer implementation to select\n sub nodes or ranges. A flexible Input/Output mechanism\n is available, with existing HTTP and FTP modules and\n combined to an URI library.Security Fix(es):** DISPUTED\n ** libxml2 2.9.4, when used in recover mode, allows\n remote attackers to cause a denial of service (NULL\n pointer dereference) via a crafted XML document. NOTE:\n The maintainer states 'I would disagree of a CVE with\n the Recover parsing option which should only be used\n for manual recovery at least for XML\n parser.'(CVE-2017-5969)A NULL pointer dereference\n vulnerability exists in the\n xpath.c:xmlXPathCompOpEval() function of libxml2\n through 2.9.8 when parsing an invalid XPath expression\n in the XPATH_OP_AND or XPATH_OP_OR case. Applications\n processing untrusted XSL format inputs with the use of\n the libxml2 library may be vulnerable to a denial of\n service attack due to a crash of the\n application.(CVE-2018-14404)libxml2 2.9.8, if\n --with-lzma is used, allows remote attackers to cause a\n denial of service (infinite loop) via a crafted XML\n file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated\n by xmllint, a different vulnerability than\n CVE-2015-8035 and CVE-2018-9251.(CVE-2018-14567)libxml2\n 20904-GITv2.9.4-16-g0741801 is vulnerable to a\n heap-based buffer over-read in the\n xmlDictComputeFastKey function in dict.c. This\n vulnerability causes programs that use libxml2, such as\n PHP, to crash.

CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. \"Affected Products and Versions\" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.\n\n## Document Location\n\nWorldwide\n\n[{\"Business Unit\":{\"code\":\"BU053\",\"label\":\"Cloud & Data Platform\"},\"Product\":{\"code\":\"SS5K6E\",\"label\":\"IBM MQ Appliance\"},\"Component\":\"\",\"Platform\":[{\"code\":\"PF004\",\"label\":\"Appliance\"}],\"Version\":\"9.1.0.0;9.1.0.1;9.1.0.2;9.1.0.3;9.1.0.4;9.1.0.5;9.1.1;9.1.2;9.1.3;9.1.4;9.1.5\",\"Edition\":\"\",\"Line of Business\":{\"code\":\"LOB36\",\"label\":\"IBM Automation\"}}]", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.0", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2020-07-27T09:24:37", "type": "ibm", "title": "Security Bulletin: IBM MQ Appliance is affected by multiple libxml2 vulnerabilities", "bulletinFamily": "software", "cvss2": {"severity": "MEDIUM", "exploitabilityScore": 8.6, "obtainAllPrivilege": false, "userInteractionRequired": true, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "MEDIUM", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 6.8, "vectorString": "AV:N/AC:M/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "obtainUserPrivilege": false}, "cvelist": ["CVE-2015-8035", "CVE-2017-15412", "CVE-2017-18258", "CVE-2018-14567"], "modified": "2020-07-27T09:24:37", "id": "244ECED1318E3472926D72334F870E4E52EEBDA4CBF4408680F466AF6B21AED2", "href": "https://www.ibm.com/support/pages/node/6252773", "cvss": {"score": 6.8, "vector": "AV:N/AC:M/Au:N/C:P/I:P/A:P"}}, {"lastseen": "2022-06-28T22:00:04", "description": "## Summary\n\nIBM QRadar Network Security has addressed the following vulnerabilities.\n\n## Vulnerability Details\n\n**CVEID: **[CVE-2019-13734](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-13734>) \n**DESCRIPTION: **Google Chrome could allow a remote attacker to execute arbitrary code on the system, caused by an out-of-bounds write in SQLite.

CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. \"Affected Products and Versions\" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.\n\n## Document Location\n\nWorldwide\n\n[{\"Business Unit\":{\"code\":\"BU059\",\"label\":\"IBM Software w\\/o TPS\"},\"Product\":{\"code\":\"SSFSVP\",\"label\":\"IBM QRadar Network Security\"},\"Component\":\"\",\"Platform\":[{\"code\":\"PF009\",\"label\":\"Firmware\"}],\"Version\":\"5.4.0, 5.5.0\",\"Edition\":\"\",\"Line of Business\":{\"code\":\"LOB24\",\"label\":\"Security Software\"}}]", "cvss3": {"exploitabilityScore": 2.8, "cvssV3": {"baseSeverity": "HIGH", "confidentialityImpact": "HIGH", "attackComplexity": "LOW", "scope": "UNCHANGED", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "baseScore": 8.8, "vectorString": "CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H", "version": "3.0", "userInteraction": "REQUIRED"}, "impactScore": 5.9}, "published": "2021-04-09T15:15:36", "type": "ibm", "title": "Security Bulletin: IBM QRadar Network Security is affected by multiple vulnerabilities", "bulletinFamily": "software", "cvss2": {"severity": "HIGH", "exploitabilityScore": 10.0, "obtainAllPrivilege": false, "userInteractionRequired": false, "obtainOtherPrivilege": false, "cvssV2": {"accessComplexity": "LOW", "confidentialityImpact": "PARTIAL", "availabilityImpact": "PARTIAL", "integrityImpact": "PARTIAL", "baseScore": 7.5, "vectorString": "AV:N/AC:L/Au:N/C:P/I:P/A:P", "version": "2.0", "accessVector": "NETWORK", "authentication": "NONE"}, "impactScore": 6.4, "obtainUserPrivilege": false}, "cvelist": ["CVE-2015-2716", "CVE-2015-8035", "CVE-2016-10245", "CVE-2016-5131", "CVE-2017-15412", "CVE-2017-18258", "CVE-2018-14404", "CVE-2018-14567", "CVE-2019-13232", "CVE-2019-13734", "CVE-2020-5208"], "modified": "2021-04-09T15:15:36", "id": "2C79ED95B1DDF725C67F241D5C01546FA0476ABBA3CE0E75B8B5CD09C4F93D6C", "href": "https://www.ibm.com/support/pages/node/6238168", "cvss": {"score": 7.5, "vector": "AV:N/AC:L/Au:N/C:P/I:P/A:P"}}], "cloudfoundry": [{"lastseen": "2021-01-01T15:27:17", "description": "# \n\n# Severity\n\nMedium\n\n# Vendor\n\nCanonical Ubuntu\n\n# Versions Affected\n\n * Canonical Ubuntu 14.04\n * Canonical Ubuntu 16.04\n * Canonical Ubuntu 18.04\n\n# Description\n\nMatias Brutti discovered that libxml2 incorrectly handled certain XML files.
