* Security fixes:
- CVE-2024-45490, bsc#1229930 -- Calling function XML_ParseBuffer with
len < 0 without noticing and then calling XML_GetBuffer
will have XML_ParseBuffer fail to recognize the problem
and XML_GetBuffer corrupt memory.
With the fix, XML_ParseBuffer now complains with error
XML_ERROR_INVALID_ARGUMENT just like sibling XML_Parse
has been doing since Expat 2.2.1, and now documented.
Impact is denial of service to potentially artitrary code
execution.
- CVE-2024-45491, bsc#1229931 -- Internal function dtdCopy can have an
integer overflow for nDefaultAtts on 32-bit platforms
(where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
- CVE-2024-45492, bsc#1229932 -- Internal function nextScaffoldPart can
have an integer overflow for m_groupSize on 32-bit
platforms (where UINT_MAX equals SIZE_MAX).
Impact is denial of service to potentially artitrary code
execution.
