Debian DLA-2468-1 : tcpflow security update

critical Nessus Plugin ID 143323
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security update.


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.

For the detailed security status of tcpflow please refer to its security tracker page at:

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.


Upgrade the affected tcpflow, and tcpflow-nox packages.
