If your organization is running any Linux, Unix, or Mac systems, you are likely vulnerable to the ShellShock attack. The issue is with bash, a very common text shell that runs on these OSs to provide a command line UI.
Our systems have already been patched to the latest available bash package as of this post. There is the possibility for an attacker to gain control of a vulnerable machine. ShellShock is rated a 10 out of 10 on the U.S. National Vulnerability Database’s severity scale.
Please contact MCS if your organization runs any Linux or Unix servers. At this time, there is no patch available for MACs. Most Linux repos have at least a partial fix available now.
