xmlrpc-c vulnerabilities
A security issue affects these releases of Ubuntu and its
derivatives:
- Ubuntu 12.04 LTS
Summary
Several security issues were fixed in XML-RPC for C and C++.
Software description
- xmlrpc-c
– Lightweight RPC library based on XML and HTTP
Details
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)
