Details
Nokogiri version 1.6.7.1 has been released, pulling in several upstream patches to the vendored libxml2 to address the following CVEs: CVE-2015-5312 CVSS v2 Base Score: 7.1 (HIGH) The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660. CVE-2015-7497 CVSS v2 Base Score: 5.0 (MEDIUM) Heap-based buffer overflow in the xmlDictComputeFastQKey function in dict.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors. CVE-2015-7498 CVSS v2 Base Score: 5.0 (MEDIUM) Heap-based buffer overflow in the xmlParseXmlDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service via unspecified vectors related to extracting errors after an encoding conversion failure. CVE-2015-7499 CVSS v2 Base Score: 5.0 (MEDIUM) Heap-based buffer overflow in the xmlGROW function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive process memory information via unspecified vectors. CVE-2015-7500 CVSS v2 Base Score: 5.0 (MEDIUM) The xmlParseMisc function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (out-of-bounds heap read) via unspecified vectors related to incorrect entities boundaries and start tags. CVE-2015-8241 CVSS v2 Base Score: 6.4 (MEDIUM) The xmlNextChar function in libxml2 2.9.2 does not properly check the state, which allows context-dependent attackers to cause a denial of service (heap-based buffer over-read and application crash) or obtain sensitive information via crafted XML data. CVE-2015-8242 CVSS v2 Base Score: 5.8 (MEDIUM) The xmlSAX2TextNode function in SAX2.c in the push interface in the HTML parser in libxml2 before 2.9.3 allows context-dependent attackers to cause a denial of service (stack-based buffer over-read and application crash) or obtain sensitive information via crafted XML data. CVE-2015-8317 CVSS v2 Base Score: 5.0 (MEDIUM) The xmlParseXMLDecl function in parser.c in libxml2 before 2.9.3 allows context-dependent attackers to obtain sensitive information via an (1) unterminated encoding value or (2) incomplete XML declaration in XML data, which triggers an out-of-bounds heap read.
