CVE-2014-8583 mod_wsgi: failure to handle errors when attempting to drop group privileges
Last modified: 2015-07-31 03:22:21 EDT
mod_wsgi allows you to host Python applications on the Apache HTTP Server. It was reported that mod_wsgi failed to handle errors when attempting to drop group privileges. An error would be printed, but mod_wsgi would continue running with root group privileges. If an administrator has configured mod_wsgi to allow less trusted users to run a WSGI application, they could use this flaw to escalate their privileges if a group-dropping function failed. This issue has been fixed in the 4.2.4 release: http://modwsgi.readthedocs.org/en/latest/release-notes/version-4.2.4.html References: http://seclists.org/oss-sec/2014/q2/545 http://seclists.org/oss-sec/2014/q2/555
