Scientific Linux Security Update : python-paste-script on SL6.x i386/x86_64

Medium Nessus Plugin ID 61694


The remote Scientific Linux host is missing a security update.


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.

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.


Update the affected python-paste-script package.
