RPM Pkg Audit

This command-line program cn be used to query data against Redhat's Security API.

Usage:

Usage: rpm_pkg_audit.rb [options]
    -p, --pkg PKGNAME                Takes a base pkg name and returns cves from redhats security API.
    -l, --list                       List packages in the XML datafile.
    -x, --xmlpkg PKGNAME             The pkg name you want to audit from xml file rpm-to-cve.xml
    -r, --refresh                    Refresh rpm-to-cve.xml file with latest pkgs and cves
    -c, --cve CVE-2020-1234          Takes a cve id and returns cve json from redhats security API.
    -f, --cves-from-file cves.txt    Takes a file one cve id per line and sends a batch request to redhat security API
    -a, --advisory RHSA-2019:0997    Takes a RHSA advisory and sends an API request to redhat RHSA-2015:2155

--refresh

By default there needs to be a ./data directory in the project where running the script. It needs to have an XML file named rpm-to-cve.xml inside of the data dir. This file is sourced from here. You can run the --refresh command to download a fresh copy of this file.

--list

This will list out all of the packages that are present in the XML file rpm-to-cve.xml. You can pipe the output to grep to search for specific package names.

--xmlpkg

This will parse the XML file rpm-to-cve.xml for the package name given. If there are results, the output will be pretty printed to the screen.

--pkg

This will send an API query to Redhat's Security API. GET /cve.json?package=base_package_name The output will be pretty printed to the screen.

--cve

This will send an API query to Redhat's Security API. GET /cve/CVE_ID.json The output will be pretty printed to the screen.

--cves-from-file

This command expects a file to be present with one single CVE id per line. This will send X num of batch API query to Redhat's Security API depending how many are in the txt file. 500 CVE IDS per API query GET /cve/CVE_ID, CVE_ID, CVE_ID, CVE_ID, etc... The output will be pretty printed to the screen.

--advisory

This will send an API query to Redhat's Security API. GET /cve.json?advisory=ADVISORY_ID The output will be pretty printed to the screen.

helper shellscript

To filter out operating system and the package that needs to be upgraded to quickly there is a helper shellscript provided in this repo. It uses jq to quickly filter out the package needed to be upgraded from the redhat json api response data. Example usage:

./rhel_pkg_upgrade_for_cve.sh CVE-2016-3627 'Red Hat Enterprise Linux 6'                                                                                                                        [4:28:57]
{
  "cve_id": "CVE-2016-3627",
  "product_name": "Red Hat Enterprise Linux 6",
  "package_name": "libxml2-0:2.7.6-21.el6_8.1"
}

./rhel_pkg_upgrade_for_cve.sh CVE-2016-3627 'Red Hat Enterprise Linux 7' 
{
  "cve_id": "CVE-2016-3627",
  "product_name": "Red Hat Enterprise Linux 7",
  "package_name": "libxml2-0:2.9.1-6.el7_2.3"
