rpm2cvescan is an RedHat/CentOS 5/6/7/8 rpm cve vulnerability scanner based on
  * RedHat's RPM to CVE mapping:          rpm-to-cve.xml
  * RedHat's OVAL infor for RHEL5,6,7,8:  com.redhat.rhsa-RHEL5.xml, com.redhat.rhsa-RHEL6.xml, com.redhat.rhsa-RHEL7.xml, com.redhat.rhsa-RHEL8.xml
  * RedHat's RHSA to date mapping         rhsamapcpe.txt
  * RedHat's CVE 2 DATE                   cve_dates.txt

How does this work?
  Based on above files we can create a memory structure associated
  with an rpm. Each package entry will have an array of vulnerability attributes
  like cve, cve score, cve2rhsa.

  We will get an inventory of the server by running a command that will list
  all installed packages:
      # /bin/rpm --nosignature --nodigest -qa --qf '%{N}-%{epochnum}:%{V}-%{R} %{N}\n'

  Finally, we will loop through the memory structure and print info ( package name,
  cve ID and score) on screen. We also print the same information in csv format.


How to run the scanner:
  * install package dependencies using:
       centos 5,6,7 # yum -y install perl-XML-Simple perl-RPM4
       centos 8     # dnf -y install perl-XML-Simple perl-RPM4

  * download these files to be sure you have the latest revision:
       # /usr/bin/wget -N "https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL5.xml"
       # /usr/bin/wget -N "https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL6.xml"
       # /usr/bin/wget -N "https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL7.xml"
       # /usr/bin/wget -N "https://www.redhat.com/security/data/oval/com.redhat.rhsa-RHEL8.xml"

       # /usr/bin/wget -N "https://www.redhat.com/security/data/metrics/rpm-to-cve.xml"
       # /usr/bin/wget -N "https://www.redhat.com/security/data/metrics/rhsamapcpe.txt"
       # /usr/bin/wget -N "https://www.redhat.com/security/data/metrics/cve_dates.txt"

  * run the perl program:
       # perl rpm2cvescan.pl



This tool will only report information about packages used by RedHat. If custom rpms are used,
e.g. php 7.1 or httpd 2.4 , this tool is not capabale of detecting vulnerabilities simply
because rpm-to-cve.xml has info on what's installed by default on your distro version,
e.g. php 5.3 for EL6.
