ESnet (Energy Sciences Network) announces iperf-3.1.3, the latest
point/bugfix release from the iperf 3.1 codeline.

iperf-3.1.3 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.
    
This release of iperf3 also supports the use of fair-queueing-based
per-socket pacing (in recent versions of the Linux kernel).  Several
other bugs and portability fixes are also included.

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.  It 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.  Note that iperf3 is not compatible with, and
will not interoperate with, version 2 or earlier of iperf.
