|---|---|---|---|---|---|---|---|---|
| CVE-2016-0718 | Cri | 0.65 | 9.8 | 0.13 | May 26, 2016 | 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-2016-5300 | Hig | 0.49 | 7.5 | 0.07 | Jun 16, 2016 | 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-2012-6702 | Med | 0.39 | 5.9 | 0.02 | Jun 16, 2016 | 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-2015-1283 | 0.02 | — | 0.19 | Jul 23, 2015 | 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… | |||
| CVE-2009-3560 | 0.02 | — | 0.24 | Dec 4, 2009 | 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,… | |||
| CVE-2019-15903 | 0.01 | — | 0.07 | Sep 4, 2019 | 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 | 0.01 | — | 0.07 | Jun 24, 2019 | 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-2022-40674 | 0.00 | — | 0.02 | Sep 14, 2022 | libexpat before 2.4.9 has a use-after-free in the doContent function in xmlparse.c. | |||
| CVE-2022-25315 | 0.00 | — | 0.05 | Feb 18, 2022 | In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames. | |||
| CVE-2022-25313 | 0.00 | — | 0.03 | Feb 18, 2022 | 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-2022-23990 | 0.00 | — | 0.04 | Jan 26, 2022 | Expat (aka libexpat) before 2.4.4 has an integer overflow in the doProlog function. | |||
| CVE-2022-23852 | 0.00 | — | 0.05 | Jan 24, 2022 | Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. | |||
| CVE-2022-22823 | 0.00 | — | 0.03 | Jan 8, 2022 | build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. | |||
| CVE-2022-22825 | 0.00 | — | 0.03 | Jan 8, 2022 | lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow. |
