| CVE-2021-45960 | 1 Libexpat Project | 1 Libexpat | 2022-01-17 | 5.0 MEDIUM | 7.5 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). | |||||

| In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. | |||||

| CVE-2013-0340 | 1 Libexpat Project | 1 Libexpat | 2021-10-27 | 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-2018-20843 | 6 Canonical, Debian, Fedoraproject and 3 more | 6 Ubuntu Linux, Debian Linux, Fedora and 3 more | 2021-10-20 | 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-2012-0876 | 1 Libexpat Project | 1 Libexpat | 2021-07-31 | 4.3 MEDIUM | N/A |
| 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-2016-4472 | 2 Canonical, Libexpat Project | 2 Ubuntu Linux, Libexpat | 2021-07-31 | 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-2016-5300 | 4 Canonical, Debian, Google and 1 more | 4 Ubuntu Linux, Debian Linux, Android and 1 more | 2021-07-31 | 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-2016-0718 | 7 Apple, Canonical, Debian and 4 more | 12 Mac Os X, Ubuntu Linux, Debian Linux and 9 more | 2021-07-31 | 7.5 HIGH | 9.8 CRITICAL |
| Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. | |||||
| CVE-2015-1283 | 2 Google, Libexpat Project | 2 Chrome, Libexpat | 2021-07-31 | 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-2017-9233 | 1 Libexpat Project | 1 Libexpat | 2021-06-29 | 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 | 1 Libexpat Project | 1 Libexpat | 2021-06-15 | 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-2012-6702 | 4 Canonical, Debian, Google and 1 more | 4 Ubuntu Linux, Debian Linux, Android and 1 more | 2021-01-25 | 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-2012-1148 | 2 Apple, Libexpat Project | 2 Mac Os X, Libexpat | 2021-01-25 | 5.0 MEDIUM | N/A |
| 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 | 2 Apple, Libexpat Project | 2 Mac Os X, Libexpat | 2021-01-25 | 4.3 MEDIUM | N/A |
| 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. | |||||
