CVE-2015-4165

The snapshot API in Elasticsearch before 1.6.0 when another application
exists on the system that can read Lucene files and execute code from them,
is accessible by the attacker, and the Java VM on which Elasticsearch is
running can write to a location that the other application can read and
execute from, allows remote authenticated users to write to and create
arbitrary snapshot metadata files, and potentially execute arbitrary code.
