| Fixed In Version: | mod_wsgi 3.5 | Doc Type: | Bug Fix |
| Doc Text: |
It was found that mod_wsgi did not properly drop privileges if the call to setuid() failed. If mod_wsgi was set up to allow unprivileged users to run WSGI applications, a local user able to run a WSGI application could possibly use this flaw to escalate their privileges on the system.
Note: mod_wsgi is not intended to provide privilege separation for WSGI applications. Systems relying on mod_wsgi to limit or sandbox the privileges of mod_wsgi applications should migrate to a different solution with proper privilege separation.

Created python26-mod_wsgi tracking bugs for this issue: Affects: epel-5 [bug 1101871] Created mod_wsgi tracking bugs for this issue: Affects: fedora-all [bug 1101869] Affects: epel-5 [bug 1101870] 3.5 building for rawhide now http://pkgs.fedoraproject.org/cgit/mod_wsgi.git/log/ http://koji.fedoraproject.org/koji/taskinfo?taskID=6907211 Are there any plans to fix this for EL6? I didn't see any bugs open for it. Is this perhaps what BZ#1101877 is? We'll need tracking bugs for OpenShift as well python27-mod_wsgi for openshift-enterprise-2, openshift-enterprise-2.1, openshift-online python33-mod_wsgi for openshift-enterprise-2.1, openshift-online python26-mod_wsgi-3.5-1.el5, mod_wsgi-3.5-1.el5 has been pushed to the Fedora EPEL 5 stable repository. If problems still persist, please make note of it in this bug report. mod_wsgi-3.5-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. mod_wsgi-3.5-1.fc19 has been pushed to the Fedora 19 stable repository.
