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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
