Test ID:1.3.6.1.4.1.25623.1.0.881475
Category:CentOS Local Security Checks
Title:CentOS Update for python-paste-script CESA-2012:1206 centos6
Summary:The remote host is missing an update for the 'python-paste-script'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'python-paste-script'
package(s) announced via the referenced advisory.

Vulnerability Insight:
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.

Affected Software/OS:
python-paste-script on CentOS 6

Solution:
Please install the updated packages.

CVSS Score:
5.1
