Insight
Insight
The GNU Bourne Again shell (Bash) is a shell and command language interpreter compatible with the Bourne shell (sh). Bash is the default shell for Red Hat Enterprise Linux. A flaw was found in the way Bash evaluated certain specially crafted environment variables. An attacker could 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-2014-6271) For additional information on the CVE-2014-6271 flaw, refer to the Knowledgebase article linked at the references. Red Hat would like to thank Stephane Chazelas for reporting this issue. All bash users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
