USN-3013-1: XML-RPC for C and C++ vulnerabilities

Releases

• Ubuntu 12.04

Packages

• 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)
