CVE-2016-10363 Elasticsearch Logstash Denial of Service Vulnerability (ESA-2016-06)

ElasticSearch Logstash is an open source, server-side data processing pipeline that ingests data from a multitude of sources simultaneously, transforms it, and then sends it to your favorite 'stash'.

In Logstash versions prior to 2.3.3, when using the Netflow Codec plugin, a remote attacker crafting malicious Netflow v5, Netflow v9 or IPFIX packets could perform a denial of service attack on the Logstash instance. The errors resulting from these crafted inputs are not handled by the codec and can cause the Logstash process to exit.

Affected Versions:
ElasticSearch Logstash versions prior to 2.3.3 QID Detection Logic (Authenticated):
This QID checks for the installed Logstash package

A remote attacker could exploit this vulnerability to perform a denial of service attack on the Logstash instance.
