"Giampaolo Rodola discovered that the smtpd module in Python 3 did not
properly handle certain error conditions. A remote attacker could
exploit this to cause a denial of service via daemon outage. This
issue only affected Ubuntu 10.04 LTS. (CVE-2010-3493)

Niels Heinen discovered that the urllib module in Python 3 would
process Location headers that specify a file:// URL. A remote attacker
could use this to obtain sensitive information or cause a denial of
service via resource consumption. (CVE-2011-1521).

description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
