This change removes any '.' or '::' entries from /etc/environment. If a '.' or '::' is present the current working directory is included in the default search path. Rationale: Any '.' and '::' will be removed from /etc/environment. This means that any harmful programs placed in common PATH locations, would never be automatically executed. All directories must be explicitly defined within the PATH variable.
Solution
Examine PATH in /etc/environment to see if it contains any '.' or '::' entries: grep '^PATH=' /etc/environment |awk '/((:[ t]*:)|(:[ t]*$)|(^[t]*:)|(^.:)|(:.$)|(:.:))/' If the command above yields output, remove the '.' and '::' entries from: vi /etc/environment Default Value: Dot present
