Ubuntu 16.04 LTS / 18.04 LTS : tcpflow vulnerabilities (USN-3955-1)

critical Nessus Plugin ID 124322

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3955-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected tcpflow and / or tcpflow-nox packages.
