Ubuntu Security Notice USN-2364-1
September 27, 2014

bash vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Bash.

Software Description:
- bash: GNU Bourne Again SHell

Details:

Florian Weimer and Todd Sabin discovered that the Bash parser incorrectly
handled memory. An attacker could possibly use this issue to bypass certain
environment restrictions and execute arbitrary code. (CVE-2014-7186,
CVE-2014-7187)

In addition, this update introduces a hardening measure which adds prefixes
and suffixes around environment variable names which contain shell
functions.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 14.04 LTS:
bash 4.3-7ubuntu1.4

Ubuntu 12.04 LTS:
bash 4.2-2ubuntu2.5

Ubuntu 10.04 LTS:
bash 4.1-2ubuntu3.4

In general, a standard system update will make all the necessary changes.
