|---|---|---|---|---|---|
| CVE-2022-43680 | 4 Debian, Fedoraproject, Libexpat Project and 1 more | 18 Debian Linux, Fedora, Libexpat and 15 more | 2024-01-03 | N/A | 7.5 HIGH |
| In libexpat through 2.4.9, there is a use-after free caused by overeager destruction of a shared DTD in XML_ExternalEntityParserCreate in out-of-memory situations. | |||||
| CVE-2022-25313 | 5 Debian, Fedoraproject, Libexpat Project and 2 more | 6 Debian Linux, Fedora, Libexpat and 3 more | 2023-08-08 | 4.3 MEDIUM | 6.5 MEDIUM |
| In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element. | |||||
| CVE-2017-9233 | 3 Debian, Libexpat Project, Python | 3 Debian Linux, Libexpat, Python | 2022-07-28 | 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-2019-15903 | 2 Libexpat Project, Python | 2 Libexpat, Python | 2022-07-28 | 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-2021-45960 | 4 Debian, Libexpat Project, Netapp and 1 more | 7 Debian Linux, Libexpat, Active Iq Unified Manager and 4 more | 2022-07-12 | 9.0 HIGH | 8.8 HIGH |
| In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). | |||||
| CVE-2015-1283 | 8 Canonical, Debian, Google and 5 more | 13 Ubuntu Linux, Debian Linux, Chrome and 10 more | 2022-07-05 | 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 Ipad Os, Iphone Os, Macos and 4 more | 2022-07-05 | 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-2016-4472 | 4 Canonical, Libexpat Project, Mcafee and 1 more | 4 Ubuntu Linux, Libexpat, Policy Auditor and 1 more | 2022-07-05 | 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. | |||||

| 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-2012-1148 | 2 Apple, Libexpat Project | 2 Mac Os X, Libexpat | 2021-01-25 | 5.0 MEDIUM | N/A |
