It was discovered that Python built-in module CGIHTTPServer does not properly handle URL-encoded path separators in URLs which may enable attackers to disclose a CGI script’s source code or execute arbitrary scripts in the server’s document root. (CVE-2014-4650)
Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a ‘buffer’ function.
