How To Fix flawfinder: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu flawfinder is provided by flawfinder package.

flawfinder is:

Flawfinder searches through C/C++ source code looking for potential security flaws and produces a report describing the potential flaws found in source code, ranking them by likely severity.

Like RATS, Flawfinder reports are not a direct indication of a vulnerability, but provide a reasonable starting point for performing manual security audits in source code.

Flawfinder can also generate differential reports by pointing it to a patch (diff) file describing the code changes. This way it can be used to determine if the potential flaws found in code have increased or decreased after a commit to a source code management system like CVS or Subversion.

To fix this problem, we can install more using the command below.

sudo apt-get -y install flawfinder

This command might take some time to finish depending on your machine internet connection.
