"An issue has been found in tcpflow, a TCP flow recorder.

Due to an overflow vulnerability in function handle_80211, an
out-of-bounds read with access to sensitive memory or a denial of
service might happen.

For Debian 9 stretch, this problem has been fixed in version
1.4.4+repack1-3+deb8u1.

We recommend that you upgrade your tcpflow packages.
