Fabric OS v7.3.0c Release Notes v1.0 Page 5 of 52
Overview
FOS v7.3.0c is a patch release based on FOS v7.3.0b. All hardware platforms and features supported in FOS
v7.3.0b are also supported in FOS v7.3.0a.
This release contains a fix for a security vulnerability associated with OpenSSL. Software patches are apply to
the existing version of OpenSSL packages. The detail of these patches are:
• OpenSSL vulnerability: CVE-2014-3566
This release also contains a fix for the incorrect fan airflow display on Brocade 6505 and 6510. FOS versions
without this fix incorrectly report the correct Reverse or port-side exhaust fan direction as “Forward”, whereas
the correct Forward or port-side intake fan direction as “Reverse” through the chassisShow CLI command
(defect 524910). CLI command chassisShow will display the correct fan airflow direction after upgrading to
FOS v7.3.0c.
