3. Description:

 

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.

 

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)

 

Applications which directly create bash functions as environment variables

need to be made aware of changes to the way names are handled by this

update. For more information see the Knowledgebase article at

https://access.redhat.com/articles/1200223

 

Note: Docker users are advised to use "yum update" within their containers,

and to commit the resulting changes.

 

For additional information on CVE-2014-6271 and CVE-2014-7169, refer to the

aforementioned Knowledgebase article.

 

All bash users are advised to upgrade to these updated packages, which

contain a backported patch to correct this issue.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to use the

Red Hat Network to apply this update are available at

https://access.redhat.com/articles/11258

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

1146319 - CVE-2014-7169 bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)
