Security Fix(es):

xmltok_impl.c in Expat (aka libexpat) before 2.4.5 lacks certain validation of encoding, such as checks for whether a UTF-8 character is valid in a certain context.(CVE-2022-25235)

xmlparse.c in Expat (aka libexpat) before 2.4.5 allows attackers to insert namespace-separator characters into namespace URIs.(CVE-2022-25236)

In Expat (aka libexpat) before 2.4.5, there is an integer overflow in storeRawNames.(CVE-2022-25315)
