We have just launched version 3.0.009 of the RED firmware pattern update. You can download and install the firmware right away. This release is a maintenance update that features essential security updates. The update includes improvements to multiple RED firmware components that address various open CVEs related to those components. Not all of the CVEs, however, affected vulnerabilities on SD-RED devices. Apart from the security enhancements, this firmware update also addresses multiple issues.

Parents Comment
  • Hi Arvin. Thanks for reaching out. 

    Since RED firmware 3.0.008 is already downloaded but not installed on your setup, we would prefer you upgrade RED firmware first. 

    RED firmware upgrade to 3.0.008 on v18.5MR1-326 > SFOS upgrade to 19.5.1.MR1-278 > RED firmware upgrade to 3.0.009 is the suggested sequence. 

    Also, since 3.0.009 has not been released for 18.5MR1, upgrading RED first and then upgrading SFOS to receive the firmware upgrade.
