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. | |||||

CVE-2019-15903 | 2 Libexpat Project, Python | 2 Libexpat, Python | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read. | |||||
CVE-2018-20843 | 7 Canonical, Debian, Fedoraproject and 4 more | 9 Ubuntu Linux, Debian Linux, Fedora and 6 more | 2023-11-07 | 7.8 HIGH | 7.5 HIGH |
In libexpat in Expat before 2.2.7, XML input including XML names that contain a large number of colons could make the XML parser consume a high amount of RAM and CPU resources while processing (enough to be usable for denial-of-service attacks). | |||||
CVE-2017-9233 | 3 Debian, Libexpat Project, Python | 3 Debian Linux, Libexpat, Python | 2023-11-07 | 5.0 MEDIUM | 7.5 HIGH |
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. | |||||
CVE-2016-5300 | 4 Canonical, Debian, Google and 1 more | 4 Ubuntu Linux, Debian Linux, Android and 1 more | 2023-11-07 | 7.8 HIGH | 7.5 HIGH |
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. | |||||
CVE-2016-4472 | 4 Canonical, Libexpat Project, Mcafee and 1 more | 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more | 2023-11-07 | 6.8 MEDIUM | 8.1 HIGH |
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. | |||||
CVE-2015-1283 | 8 Canonical, Debian, Google and 5 more | 13 Ubuntu Linux, Debian Linux, Chrome and 10 more | 2023-11-07 | 6.8 MEDIUM | N/A |
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 | 3 Apple, Libexpat Project, Python | 7 Ipados, Iphone Os, Macos and 4 more | 2023-11-07 | 6.8 MEDIUM | N/A |
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 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. | |||||
CVE-2012-6702 | 4 Canonical, Debian, Google and 1 more | 4 Ubuntu Linux, Debian Linux, Android and 1 more | 2023-11-07 | 4.3 MEDIUM | 5.9 MEDIUM |
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. | |||||
CVE-2009-3560 | 3 Apache, Libexpat Project, Xmltwig | 3 Http Server, Libexpat, Xml-twig For Perl | 2023-11-07 | 5.0 MEDIUM | N/A |
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. |
