Shellshock Name 67: Understanding the Critical Vulnerability That Shook the Security Landscape When it comes to cybersecurity, few vulnerabilities have had a lasting impact as profound as Shellshock (CVE-2014-6271)—often referred to informally in the tech community by references like “NAME 67” due to its CVE identifier and symbolic associations. Officially recognized as a critical buffer overflow flaw in the Berkeley Internet Name Domain (BIND) DNS software, Shellshock exposed widespread risks across servers, devices, and networks worldwide when it was disclosed in September 2014. ### What is Shellshock (CVE-2014-6271)? Shellshock is a high-severity vulnerability rooted in the C programming language’s handling of environment variables within the BIND 9 DNS server—a widely deployed service critical to internet Domain Name System (DNS) operations. The flaw allows attackers to execute arbitrary code remotely simply by triggering a specially crafted input, such as a malformed HTTP request or DNS query. The vulnerability lies in insufficient bounds checking during string parsing, enabling a buffer overflow that can lead to code injection.
