All security tools produce false positives, and this should not be treated any differently.  If you are having trouble with this report,  I suggest seeking a different approach to testing,  perhaps one that isn't  dependent on a broken tool.

That being said httpd-2.2.15-26.el6.centos.x86_64 was released on March 2nd 2013, and there have been a couple of vulnerabilities found in Apache since March 2nd.  It would be best to manually verify that you are not affected by these exposures.

I'm replacing this simple 2-connector light switch with a 4-wire dimmer. The 2 new wires present on the dimmer are neutral and ground, and only neutral has an obvious home. The box has no visible ground wires. Can I safely ground the dimmer to a box screw or leave the dimmer ground wire disconnected?
