RHSA-2022:7692: Moderate: xmlrpc-c security update

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 buildmodel 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) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.Additional Changes:For detailed information on changes in this release, see the Red Hat Enterprise Linux 8.7 Release Notes linked from the References section.
