Ubuntu sent a third patch out:
Quote:
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.
