Preventing Zero Day Vulnerabilities

Today, zero-day vulnerabilities are common. Notorious examples include the recent Stuxnet and Operation Aurora exploits. Vulnerabilities may arise from a variety of sources, but most vulnerabilities are the result of simple coding errors. Consequently, developers need to understand common traps and pitfalls in the programming language, libraries, and platform to produce code that is free of vulnerabilities. To address this problem, CERT published The CERT Oracle Coding Standard for Java in 2011. This book is version 1 of this standard and was written primarily for Java SE 6, but also covers features introduced in Java SE 7. This coding standard provides secure coding rules that help programmers recognize and avoid vulnerabilities in their products. Each rule provides simple instructions regarding what a programmer must and must not do. Each rule description is accompanied by noncompliant code examples, as well as compliant solutions that can be used instead. In this blog post, I examine a Java zero-day vulnerability, CVE 2012-0507, which infected half a million Macintosh computers, and consider how this exploit could have been prevented through adherence to two secure coding rules.
