27 Jan 2020
Affected Packages:
Security database references:
In the Debian bugtracking system: Bug 827116.
In Mitre's CVE dictionary: CVE-2016-4303.
More information:

An issue has been found in iperf3, an Internet Protocol bandwidth measuring tool. Bad handling of UTF8/16 strings in an embedded library could cause a denial of service (crash) or execution of arbitrary code by putting special characters in a JSON string, which triggers a heap-based buffer overflow.

For Debian 8 Jessie, this problem has been fixed in version 3.0.7-1+deb8u1.

We recommend that you upgrade your iperf3 packages.
