Linux Daemons with Broken Links to Executables

info Nessus Plugin ID 44657

Language:

Synopsis

A daemon on the remote Linux host may need to be restarted.

Description

By examining the '/proc' filesystem on the remote Linux host, Nessus has identified at least one currently-running daemon for which the link to the corresponding executable is broken.

This can occur when the executable associated with a daemon is replaced on disk but the daemon itself has not been restarted. And if the changes are security-related, the system may remain vulnerable to attack until the daemon is restarted.

Alternatively, it could result from an attacker removing files in an effort to hide malicious activity.

Solution

Inspect each reported daemon to determine why the link to the executable is broken.
