I would like bring to your attention a new vulnerability that has been found that potentially affects most versions of the Linux and Unix operating systems, in addition to Mac OS X (which is based around Unix). Known as the “Bash Bug” or “Shellshock,” the GNU Bash Remote Code Execution Vulnerability (CVE-2014-6271) could allow an attacker to gain control over a targeted computer if exploited successfully.

The vulnerability affects Bash, a common component known as a shell that appears in many versions of Linux and Unix. Bash acts as a command language interpreter. In other words, it allows the user to type commands into a simple text-based window, which the operating system will then run.

Please review the following document from the Symantec Security Blog for further details:
