Summary
expat security update
Details

An XML parser library.

Security Fix(es):

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-2021-45960)

lookup in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22825)

storeAtts in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22827)

addBinding in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22822)

nextScaffoldPart in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22826)

build_model in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22823)

defineAttribute in xmlparse.c in Expat (aka libexpat) before 2.4.3 has an integer overflow.(CVE-2022-22824)

In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize.(CVE-2021-46143)
