2024-08-30 CVE-2024-45491 An issue was discovered in libexpat before 2.6.3. dtdCopy in xmlparse.c can have an integer overflow for nDefaultAtts on 32-bit platforms (where UINT_MAX equals SIZE_MAX). Libexpat 9.8
2024-08-30 CVE-2024-45492 An issue was discovered in libexpat before 2.6.3. nextScaffoldPart in xmlparse.c can have an integer overflow for m_groupSize on 32-bit platforms (where UINT_MAX equals SIZE_MAX). Libexpat 9.8
2009-11-03 CVE-2009-3720 The updatePosition function in lib/xmltok_impl.c in libexpat in Expat 2.0.1, as used in Python, PyXML, w3c-libwww, and other software, allows context-dependent attackers to cause a denial of service (application crash) via an XML document with crafted UTF-8 sequences that trigger a buffer over-read, a different vulnerability than CVE-2009-2625. Http_server, Libexpat N/A
2009-12-04 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 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 CVE-2009-2625 and CVE-2009-3720. Http_server, Libexpat N/A
2014-01-21 CVE-2013-0340 expat 2.1.0 and earlier 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) issue. NOTE: it could be argued that because expat already provides the ability to disable external entity expansion, the responsibility for... Ipados, Iphone_os, Macos, Tvos, Watchos, Libexpat, Python N/A
2015-07-23 CVE-2015-1283 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. Ubuntu_linux, Debian_linux, Chrome, Libexpat, Leap, Opensuse, Solaris, Python, Linux_enterprise_debuginfo, Linux_enterprise_desktop, Linux_enterprise_server, Linux_enterprise_software_development_kit, Studio_onsite N/A
2016-06-16 CVE-2012-6702 Expat, when used in a parser that has not called XML_SetHashSalt or passed it a seed of 0, makes it easier for context-dependent attackers to defeat cryptographic protection mechanisms via vectors involving use of the srand function. Ubuntu_linux, Debian_linux, Android, Libexpat 5.9
2016-06-16 CVE-2016-5300 The XML parser in Expat does not use sufficient entropy for hash initialization, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted identifiers in an XML document. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-0876. Ubuntu_linux, Debian_linux, Android, Libexpat 7.5
2016-06-30 CVE-2016-4472 The overflow protection in Expat is removed by compilers with certain optimization settings, which allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted XML data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1283 and CVE-2015-2716. Ubuntu_linux, Libexpat, Policy_auditor, Python 8.1
2017-07-25 CVE-2017-9233 XML External Entity vulnerability in libexpat 2.2.0 and earlier (Expat XML Parser Library) allows attackers to put the parser in an infinite loop using a malformed external entity definition from an external DTD. Debian_linux, Libexpat, Python 7.5
