Summary

XML-RPC is a remote procedure call (RPC) protocol that uses XML to encode its calls and HTTP as a transport mechanism. The xmlrpc-c packages provide a network protocol to allow a client program to make a simple RPC (remote procedure call) over the Internet. It converts an RPC into an XML document, sends it to a remote server using HTTP, and gets back the response in XML.
Security Fix(es):
* expat: Integer overflow in doProlog in xmlparse.c (CVE-2021-46143)
* expat: Integer overflow in addBinding in xmlparse.c (CVE-2022-22822)
* expat: Integer overflow in build_model in xmlparse.c (CVE-2022-22823)
* expat: Integer overflow in defineAttribute in xmlparse.c (CVE-2022-22824)
* expat: Integer overflow in lookup in xmlparse.c (CVE-2022-22825)
* expat: Integer overflow in nextScaffoldPart in xmlparse.c (CVE-2022-22826)
* expat: Integer overflow in storeAtts in xmlparse.c (CVE-2022-22827)
