[SinghHrmn]

Added gnutls file test for version 2.3.11. The 2.3.11 version was downloaded from the official gnutls website. All the test were fine. I've attached the test screenshot

@terriko @pdxjohnny I'd like to mention a problem with gnutls checker. The checker was unable to find the CVE's in the given version as you can see from the below output

mastervulcan@DESKTOP-DMEM457:~/gsoc-cve-bin-tool$ cve-bin-tool ./testFilesCVE-bin-tool/gnutls-2.3.11/
Checking if CVE data needs an update.
Last Update: 2020-01-28
Local database has been updated in the past 24h.
New data not downloaded.  Use "-u now" to force an update

Overall CVE summary: 
There are 0 files with known CVEs detected

where ./testFilesCVE-bin-tool/gnutls-2.3.11/ is the location where I've extracted gnutls-2.3.11.tar.bz2 file. The File test which I've written uses the same file. But the test said ok.

@SinghHrmn That happens sometimes if it finds a version but doesn't find any CVEs associated with that version -- the file test checks if this is 2.3.11 as you said it was, but it doesn't look for CVEs. You can check to see what it thinks it found by using --log debug right now. If it's not finding anything, this might be a bug so please file an issue for it so we can investigate further.

Hm, put some more thought into this:

• test_gnutls_bz2_2_3_11 will pass if gnutls 2.3.11 is found.
• the cli will only print versions if cves are found.

If cve-bin-tool thinks for some reason that there are no CVEs in 2.3.11 exist, then what you're seeing would be normal behaviour. But 2.3.11 is pretty old, so I put it in a csv file to test and got some results. So that definitely looks like a bug.
