Red Hat Security Advisory
Synopsis: Important: mod_wsgi security update
Advisory ID: RHSA-2014:1091-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1091.html
Issue date: 2014-08-25
CVE Names: CVE-2014-0240
An updated mod_wsgi package that fixes one security issue is now available
for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
2. Relevant releases/architectures:
Red Hat Enterprise Linux Client Optional (v. 7) - x86_64
Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64
Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation (v. 7) - x86_64
The mod_wsgi adapter is an Apache module that provides a WSGI-compliant
interface for hosting Python-based web applications within Apache.
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.
Red Hat would like to thank Graham Dumpleton for reporting this issue.
Upstream acknowledges RÃƒÂ³bert Kisteleki as the original reporter.
All mod_wsgi users are advised to upgrade to this updated package, which
contains a backported patch to correct this issue.
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
