In this era where almost everything is online, online security is a major concern. These days, a lot of web servers, web-connected devices, and services use Linux as their platform. Most versions of Linux use the Unix bash shell, so the Shellshock vulnerability can affect a huge number of websites and web servers.
Shellshock was discovered on September 12, 2014, and it affects all the distributions of Linux using a Bash shell. The Shellshock vulnerability makes it possible to execute commands remotely using environment variables.
In this free downloadable chapter from Packt Publishing’s Linux Security Cookbook, discover more about the Shellshock vulnerability and how to patch and deal with Bash vulnerabilities for better Linux security.
