IRIX 6.5: GEN001366 (in versions v1 r1 through v1 r0.6)

Title

The /etc/hosts file must be owned by root. (Cat II impact)

Discussion

The /etc/hosts file (or equivalent) configures local host name to IP address mappings that typically take precedence over DNS resolution. If this file is maliciously modified, it could cause the failure or compromise of security functions requiring name resolution, which may include time synchronization, centralized authentication, and remote system logging.

Check Content

Verify the /etc/hosts file is owned by root. Procedure: # ls -lL /etc/hosts If the file is not owned by root, this is a finding.

Fix Text

Change the owner of the /etc/hosts file to root. # chown root /etc/hosts
