Moderate: xmlrpc-c security update

Published Nov 8, 2022 · Updated Oct 29, 2026

Ecosystem: AlmaLinux

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.
