GLIBC DNS Vulnerability

You need to update your Linux server's installation of glibc immediately to protect it from a stack-based buffer overflow which was discovered on February 16, 2016.

Note: You only need to perform this update if you have a VPS or dedicated server. Customers with shared hosting accounts do not need to do anything.
