ESnet (Energy Sciences Network) announces the public release
of iperf-3.0.12, the latest point/bugfix release from the iperf 3.0
codeline.

iperf-3.0.12 fixes an important security issue in all previous versions
of iperf3.  That issue was a buffer overflow / heap corruption issue
that could occur if a malformed JSON string was passed on the control
channel.  In theory, it could be leveraged to create a heap exploit.
This vulnerability was discovered and reported by Dave McDaniel, Cisco
Talos.  More information can be found in security advisories
TALOS-CAN-0164 and ESNET-SECADV-2016-0001.  The CVE identifier
CVE-2016-4303 has been assigned for this vulnerability.
    
More information on changes can be found in the RELEASE_NOTES
file in the source distribution.

iperf3 is a tool for measuring the maximum TCP and UDP performance
along a path, allowing for the tuning of various parameters and
reporting measurements such as throughput, jitter, and datagram packet
loss.

The original iperf was implemented by NLANR / DAST.  Version 3 is a
complete reimplementation, with the goals of a smaller, simpler code
base, and a library that can be used by other programs.  It also adds
new functionality, such as CPU utilization measurements, zero copy TCP
support, and JSON output.  Note that iperf3 clients and servers are
not compatible with, and will not interoperate with, earlier versions
of iperf.

iperf3 is fully supported on Linux, FreeBSD, and MacOS X.  It may run
on other platforms as well, although it has not received the same
attention and testing.
