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.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
