Splunk 6.x < 6.0.3 Multiple OpenSSL Vulnerabilities (Heartbleed)

Synopsis :

The remote web server contains an application that is affected by
multiple OpenSSL-related vulnerabilities.

Description :

According to its version number, the Splunk Web hosted on the remote
web server is 6.x prior to 6.0.3. It is, therefore, affected by
multiple OpenSSL-related vulnerabilities :

- A flaw exists with the OpenSSL version being used by
Splunk with the 'ssl3_take_mac' in 'ssl/s3_both.c'. This
allows a remote attacker to cause a denial of service
with a specially crafted request. (CVE-2013-4353)

- An out-of-bounds read error, known as Heartbleed, exists
in the TLS/DTLS implementation due to improper handling
of TLS heartbeat extension packets. A remote attacker,
using crafted packets, can trigger a buffer over-read,
resulting in the disclosure of up to 64KB of process
memory, which contains sensitive information such as
primary key material, secondary key material, and other
protected content. (CVE-2014-0160)

Note that Nessus has not tested for these issues but has instead
relied only on the application's self-reported version number.
