Details
Brocade Fabric OS (FOS) hardware
platforms running any version of Brocade Fabric OS software, which
supports the license string format; contain cryptographic
issues that could allow for the installation of forged or fraudulent
license keys. This would allow attackers or a malicious party to forge a
counterfeit license key that the Brocade Fabric OS platform would
authenticate and activate as if it were a legitimate license key.
