    Has anyone upgraded to v5.4.9?  Is anyone experiencing any issues with v5.4.8 to justify upgrading to v5.4.9?
     
    Our organization recently adopted v5.4.8 and have not experienced any issues as of late with approximately 100+ Fortigates of varying models running full UTMs.

    It is generally considered a best practice to keep your Fortigate up to date with the latest version installed. One of the main benefits is patching previously discovered vulnerabilities. Have a look at the link below for issues related to specific versions of Fortigate:

    nick22d - Thanks for the reply.  Unfortunately, as a large MSSP for predominately financial institutions, we cannot upgrade our customers' Fortigates to a new FortiOS just because it's the "latest version".  All the HA and GUI bugs that arose in FortiOS v5.4.6 and v5.4.7 are great examples of why one should not blindly upgrade to the new firmware iteration before extensive testing is complete.

    There are two CVE's i can't find any information on, only that the numbers are reserved.
    Anyone know more?

    Upgraded a couple of development / test firewalls from 5.4.8 to 5.4.9.    Don't see any issues associated to the upgrade.
     
    Will report as I ssslllloooowwwwllly roll this upgrade out to various production firewalls.

    we upgrade our forti OS form 5.4.8 to 5.4.9
    Reason for the upgrade is a potentially vulnerable leak.
