DESCRIPTION:
A security issue has been reported in Python, which can be exploited
by malicious people to disclose potentially sensitive information or
cause a DoS (Denial of Service).
The security issue is caused due to the urllib/urlib2 redirect
handling allowing "file://" URL schemes, which can be exploited to
e.g. disclose potentially sensitive information or cause a high
resource consumption by returning specially crafted HTTP redirect
responses to a Python application using the urllib or urllib2 module.
SOLUTION:
Restrict "file://" URL schemes using a firewall with filtering
capabilities.
PROVIDED AND/OR DISCOVERED BY:
Reported to the vendor by an unknown person.
