Permit local access for trusted individuals only. Where possible, use restricted environments and restricted shells.
Allow only trusted individuals to have user accounts and local access to the resources.
Block external access at the network boundary, unless external parties require service.
Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
Communicate sensitive information through secure means.
Implement multiple layers of security, including transmitting potentially sensitive information through encrypted channels to reduce exposure to this and other latent vulnerabilities.
Updates are available. Please see the references or vendor advisory for more information.
