Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS

Summary:

tcpflow could be made to crash or expose sensitive information over the network if it opened a specially crafted file or received specially crafted network traffic.

Software Description: - tcpflow: TCP flow recorder

Details:

It was discovered that tcpflow incorrectly handled certain malformed network packets. A remote attacker could send these packets to a target system, causing tcpflow to crash or possibly disclose sensitive information.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 18.10:
tcpflow 1.4.5+repack1-4ubuntu0.18.10.1
tcpflow-nox 1.4.5+repack1-4ubuntu0.18.10.1

Ubuntu 18.04 LTS:
tcpflow 1.4.5+repack1-4ubuntu0.18.04.1

Ubuntu 16.04 LTS:
tcpflow 1.4.5+repack1-1ubuntu0.1
tcpflow-nox 1.4.5+repack1-1ubuntu0.1

In general, a standard system update will make all the necessary changes.
