Patching Your Redhat Server for the Shellshock Vulnerability

Introduction Alright guys, this is a biggie. Shellshock allows remote code execution and file creation for any server relying on bash v3.4 through v1.1. If you are using Redhat or CentOS and the default shell, your server is vulnerable. The patching history was sketchy, as well.

ASPY.a - Malware Source Identified as Blackhat Control Panel Developer

It takes advantage of vulnerable ASP scripts, uploads itself to a web server and in unpatched systems that lack sensible permissions policies and the latest updates, it can grant remote attackers administrator access. Microsoft Security Essentials will catch it, however I've seen at least one version of Symantec that does not completely remove compromised files - with Symantec server-level compromise was prevented, but the website itself remained controllable. So why am I writing a post about a 2 year old piece of malware? The story here is that the circulation appears to be driven by a developer based in Russia that sells "server control panel" (панель управления сервером, управление) software for novices tasked with IIS-based website management. The name of the company is...
