1. Summary:

An update for xmlrpc-c is now available for Red Hat Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat CodeReady Linux Builder (v. 8) - aarch64, ppc64le, s390x, x86_64
Red Hat Enterprise Linux BaseOS (v. 8) - aarch64, ppc64le, s390x, x86_64

3. Description:

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)
