 Problem Description:

 It was found that the fix for CVE-2014-6271 was incomplete, and
 Bash still allowed certain characters to be injected into other
 environments via specially crafted environment variables. An
 attacker could potentially use this flaw to override or bypass
 environment restrictions to execute shell commands. Certain
 services and applications allow remote unauthenticated attackers to
 provide environment variables, allowing them to exploit this issue
 (CVE-2014-7169).
 
 Additionally bash has been updated from patch level 37 to 48

Shellshock, the security hole in Bash that affects Linux and OS X

Shellshock

A security hole has been discovered in Bash that jeopardizes the security of Linux and Mac users. This vulnerability, dubbed ‘Shellshock’, affects the command interpreter in these operating systems.

So what does this mean? To give you an idea, this flaw could allow a cyber-criminal to remotely access a system using Bash and insert spyware designed to steal confidential information or even take control of the system.

The hole was discovered by Stephane Schazeblas and it would appear that it is more serious than Heartbleed, the vulnerability discovered in the OpenSSL library last April. According to the CVSS rating of the security hole, Shellshock has a score of 10, while Heartbleed was rated 5.

What can you do to protect yourself from the Bash vulnerability? Update your software and keep your operating system up-to-date.
