"It was discovered that the Expat code in XML-RPC for C and C++
unexpectedly called srand in certain circumstances. This could reduce
the security of calling applications. (CVE-2012-6702)

It was discovered that the Expat code in XML-RPC for C and C++
incorrectly handled seeding the random number generator. A remote
attacker could possibly use this issue to cause a denial of service.
(CVE-2016-5300)

Gustavo Grieco discovered that the Expat code in XML-RPC for C and C++
incorrectly handled malformed XML data. If a user or application
linked against XML-RPC for C and C++ were tricked into opening a
crafted XML file, an attacker could cause a denial of service, or
possibly execute arbitrary code. (CVE-2016-0718)
