Use NMAP to detect OPENSSL heartbleeding vulnerability

NMAP 6.46 (http://nmap.org/download.html) includes the openssl heartbleed script:

To use it, below is a sample command:
nmap -sV -v -p 0-65535 --script=ssl-heartbleed -iL ./hosts.txt -oX ./result.xml
Parameter description:
-sV: Probe open ports to determine service/version info
-v: Increase verbosity level
-iL : Input from list of hosts/networks
-oX: output scan in XML format.
A sample output as below:

If for some reason, you cannot install nmap 6.46, you can manually download ssl-heartbleed.nse from http://nmap.org/nsedoc/scripts/ssl-heartbleed.html and put it in the NMAP scripts folder. You may need tls library to run the heartbleed script. Download it from http://nmap.org/nsedoc/lib/tls.html and put it in NMAP nselib folder.
