descriptionThis Solaris system is missing necessary patches to address critical security updates : - Vulnerability in the Oracle Solaris product of Oracle Systems (component: Kernel). The supported version that is affected is 11. Easily exploitable vulnerability allows unauthenticated attacker with network access via SMB to compromise Oracle Solaris. While the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Solaris.
