Red Hat Security Advisory
Synopsis: Moderate: python-jinja2 security update
Advisory ID: RHSA-2014:0747-01
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0747.html
Issue date: 2014-06-11
CVE Names: CVE-2014-1402
=====================================================================
1. Summary:
Updated python-jinja2 packages that fix one security issue are now
available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64
Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64
Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64
Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64
3. Description:
Jinja2 is a template engine written in pure Python. It provides a
Django-inspired, non-XML syntax but supports inline expressions and an
optional sandboxed environment.
It was discovered that Jinja2 did not properly handle bytecode cache files
stored in the system's temporary directory. A local attacker could use this
flaw to alter the output of an application using Jinja2 and
FileSystemBytecodeCache, and potentially execute arbitrary code with the
privileges of that application. (CVE-2014-1402)
All python-jinja2 users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. For the update to
take effect, all applications using python-jinja2 must be restarted.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to use the
Red Hat Network to apply this update are available at
https://access.redhat.com/site/articles/11258
5. Bugs fixed (https://bugzilla.redhat.com/):
