Synopsis
========
A parsing flaw related to functions and environments in Bash could
allow attackers to inject code. The unaffected packages listed in GLSA
201409-09 had an incomplete fix.
Background
==========
Bash is the standard GNU Bourne Again SHell.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-shells/bash < 4.2_p48-r1 *>= 3.1_p18-r1
*>= 3.2_p52-r1
*>= 4.0_p39-r1
*>= 4.1_p12-r1
>= 4.2_p48-r1
Description
===========
Stephane Chazelas reported that Bash incorrectly handles function
definitions, allowing attackers to inject arbitrary code
(CVE-2014-6271). Gentoo Linux informed about this issue in GLSA
201409-09.
Tavis Ormandy reported that the patch for CVE-2014-6271 was incomplete.
As such, this GLSA supersedes GLSA 201409-09.
Impact
======
A remote attacker could exploit this vulnerability to execute arbitrary
commands even in restricted environments.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Bash 3.1 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-3.1_p18-r1"
All Bash 3.2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-3.2_p52-r1"
All Bash 4.0 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-4.0_p39-r1"
All Bash 4.1 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-4.1_p12-r1"
All Bash 4.2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-shells/bash-4.2_p48-r1"
