RedHat: RHSA-2014-0748:01 Moderate: python33-python-jinja2 and
Summary
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 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 Jinja2 must be restarted.
