addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2022-22823

build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2022-22824

defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2022-22825

lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2022-22826

nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2022-22827

storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.

CVE-2021-46143

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

CVE-2021-45960

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-2019-15903

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

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).
