Red Hat Security Advisory 2014-1312-01 – The GNU Bourne Again shell is a shell and command language interpreter compatible with the Bourne shell. Bash is the default shell for Red Hat Enterprise Linux. Shift_JIS, also known as “SJIS”, is a character encoding for the Japanese language. This package provides bash support for the Shift_JIS encoding. 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.
