Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.

Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure database servers and other applications to run as a nonadministrative user with minimal access rights.
