Synopsis
Critical: bash security update
Type/Severity
Security Advisory: Critical
Topic
Updated bash packages that fix one security issue are now available for Red
Hat Enterprise Linux 4 Extended Life Cycle Support, Red Hat Enterprise
Linux 5.6 Long Life, Red Hat Enterprise Linux 5.9 Extended Update Support,
Red Hat Enterprise Linux 6.2 Advanced Update Support, and Red Hat
Enterprise Linux 6.4 Extended Update Support.
Red Hat Product Security has rated this update as having Critical security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.
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.
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 at https://access.redhat.com/articles/1200223
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.
