Recommendations

Please review your environment to ensure the above-mentioned issues are patched in a timely manner.  It is security best practice to regularly update and/or patch software to the latest versions.  The vulnerabilities above highlight the security benefits of limiting deployed software to "vendor-supported versions" only.  This dramatically increases the likelihood that new vulnerabilities have a patch issued for them.  Likewise, Cybersafe strongly encourages maintaining an inventory of current software in your environment, which helps ensure and inform your patch and vulnerability management program.
