- update to 2.4.3 (bsc#1194251, bsc#1194362, bsc#1194474, 
     bsc#1194476, bsc#1194477, bsc#1194478, bsc#1194479, bsc#1194480):
  * 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.
  * 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.
  * 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
