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

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