This patch release to FreeNAS 11.1-U6 primarily addresses a critical security vulnerability in Netatalk (CVE-2018-1160). While Netatalk is included in FreeNAS, this particular vulnerability only impacts those who have the AFP service enabled.

This patch release includes fixes from TrueNAS 11.1-U6.1 and 11.1-U6.2 that address several FreeBSD and Samba vulnerabilities. It also includes several SMART fixes.

FreeNAS 11.1-x users are encouraged to update to U6.3 using the instructions in the Guide. FreeNAS users who are running versions prior to FreeNAS 11.1-U6 are still vulnerable and should make a plan to update. Always backup your system configuration and verify the integrity of your backups before updating.
