"An updated python-paste-script package that fixes one security issue
is now available for Red Hat Enterprise Linux 6.

The Red Hat Security Response Team has rated this update as having
moderate 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.

Python Paste provides middleware for building and running Python web
applications. The python-paste-script package includes paster, a tool
for working with and running Python Paste applications.

It was discovered that paster did not drop supplementary group
privileges when started by the root user. Running 'paster serve' as
root to start a Python web application that will run as a non-root
user and group resulted in that application running with root group
privileges. This could possibly allow a remote attacker to gain access
to files that should not be accessible to the application.
(CVE-2012-0878)

All paster users should upgrade to this updated package, which
contains a backported patch to resolve this issue. All running paster
instances configured to drop privileges must be restarted for this
update to take effect."
