Updated python-jinja2 packages fix security vulnerability: Jinja2, a template engine written in pure python, was found to use /tmp as a default directory for jinja2.bccache.FileSystemBytecodeCache, which is insecure because the /tmp directory is world-writable and the filenames used like 'FileSystemBytecodeCache' are often predictable. A malicious user could exploit this bug to execute arbitrary code as another user. (CVE-2014-1402)
