   Release 2.4.3 Sun January 16 2022
           Security fixes:
          #531 #534  CVE-2021-45960 -- Fix issues with left shifts by >=29 places
                       resulting in
                         a) realloc acting as free
                         b) realloc allocating too few bytes
                         c) undefined behavior
                       depending on architecture and precise value
                       for XML documents with >=2^27+1 prefixed attributes
                       on a single XML tag a la
                       "<r xmlns:a='[..]' a:a123='[..]' [..] />"
                       where XML_ParserCreateNS is used to create the parser
                       (which needs argument "-n" when running xmlwf).
                       Impact is denial of service, or more.
          #532 #538  CVE-2021-46143 (ZDI-CAN-16157) -- Fix integer overflow
                       on variable m_groupSize in function doProlog leading
                       to realloc acting as free.
                       Impact is denial of service or more.
               #539  CVE-2022-22822 to CVE-2022-22827 -- Prevent integer overflows
                       near memory allocation at multiple places.  Mitre assigned
                       a dedicated CVE for each involved internal C function:
                       - CVE-2022-22822 for function addBinding
                       - CVE-2022-22823 for function build_model
                       - CVE-2022-22824 for function defineAttribute
                       - CVE-2022-22825 for function lookup
                       - CVE-2022-22826 for function nextScaffoldPart
                       - CVE-2022-22827 for function storeAtts
                       Impact is denial of service or more.
