Hi Mariano, all,

It seems that this tool does not detect all CVEs, e.g. bind has some CVE patches
but it is not reported, I tried all options below nothing is reported (no cve.log file):
bitbake -c cve_check bind 
bitbake -k -c cve_check universe
bitbake -k -c cve_check world

There are some CVEs in bind (reported in nvd.xml file for our version cpe:/a:isc:bind:9.10.3"/> )
but cve.check-tool does not report them ex: (CVE-2016-2776). Do you know why?

CVEs are reported for the following packages using e.g. "bitbake -k -c cve_check universe"
or  "bitbake -c cve_check perl"

tmp/work/i586-poky-linux/perl/5.22.1-r0/cve/cve.log
tmp/work/i586-poky-linux/foomatic-filters/4.0.17-r1/cve/cve.log

tmp/work/i586-poky-linux/glibc/2.24-r0/cve/cve.log
tmp/work/i586-poky-linux/unzip/1_6.0-r5/cve/cve.log
tmp/work/i586-poky-linux/expat/2.2.0-r0/cve/cve.log
tmp/work/i586-poky-linux/gnutls/3.5.3-r0/cve/cve.log
tmp/work/i586-poky-linux/glibc-initial/2.24-r0/cve/cve.log
tmp/work/i586-poky-linux/libxml2/2.9.4-r0/cve/cve.log
tmp/work/i586-poky-linux/bzip2/1.0.6-r5/cve/cve.log

We have more recipes which have CVE patches but they are not reported. 
I have analyzed these; some of these CVEs are still marked as reserved on Mitre
 and are not present in the nvd.xml files (although they are public (e.g. Busybox: 
https://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-2147).

I don't understand why for instance bind CVEs are not detected and reported by cve-check tool?
Is it because of cpe:/a:isc:bind? It looks for isc?
