Topic: Bourne Again Shell (Bash) Remote Code Execution Vulnerability
US-CERT is aware of a Bash vulnerability affecting Unix-based operating systems such as Linux and Mac OS X. Exploitation of this vulnerability may allow a remote attacker to execute arbitrary code on an affected system.
The flaw was originally assigned CVE-2014-6271, but it was later discovered that the patch had an issue in the parser and did not fully address the problem. MITRE later assigned CVE-2014-7169 to cover the remaining problems after the application of the first patch.
US-CERT recommends users and administrators review the Redhat Security Blog(link is external) for additional details and to refer to their respective Linux or Unix-based OS vendor(s) for an appropriate patch. A GNU Bash patch is also available for experienced users and administrators to implement.
Operating systems with updates include:
•CentOS
•Debian
•Redhat(link is external)
•Ubuntu
