CVE-2015-1283 [MEDIUM] CWE-190 CVE-2015-1283: Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google C Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.

CVE-2013-0340 [MEDIUM] CWE-611 CVE-2013-0340: expat before version 2.4.0 does not properly handle entities expansion unless an application develop expat before version 2.4.0 does not properly handle entities expansion unless an application developer uses the XML_SetEntityDeclHandler 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

CVE-2012-1148 [MEDIUM] CWE-399 CVE-2012-1148: Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-de Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.

CVE-2012-1147 [MEDIUM] CWE-20 CVE-2012-1147: readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service readfilemap.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (file descriptor consumption) via a large number of crafted XML files.

CVE-2012-0876 [MEDIUM] CWE-400 CVE-2012-0876: The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the abili The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value.

CVE-2009-3560 [MEDIUM] CVE-2009-3560: The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module The big2_toUtf8 function in lib/xmltok.c in libexpat in Expat 2.0.1, as used in the XML-Twig module for Perl, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with malformed UTF-8 sequences that trigger a buffer over-read, related to the doProlog function in lib/xmlparse.c, a different vulnerability than C
