Red Hat Security Advisory 2012-1206-01 - 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.
