Several vulnerabilities were discovered in Django, a high-level Python web development framework: CVE-2015-5143 Eric Peterson and Lin Hua Cheng discovered that a new empty record used to be created in the session storage every time a session was accessed and an unknown session key was provided in the request cookie. This could allow remote attackers to saturate the session store or cause other users" session records to be evicted. CVE-2015-5144 Sjoerd Job Postmus discovered that some built-in validators did not properly reject newlines in input values. This could allow remote attackers to inject headers in emails and HTTP responses.
