Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS

Summary:

Applications using certain Python 3 modules could be made to crash or expose sensitive information over the network.

Software Description: - python3.1: An interactive high-level object-oriented language (version 3.1) - python3.2: An interactive high-level object-oriented language (version 3.2)

Details:

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)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 11.04:
python3.1-minimal 3.1.3-1ubuntu1.1
python3.2-minimal 3.2-1ubuntu1.1

Ubuntu 10.10:
python3.1-minimal 3.1.2+20100915-0ubuntu4.1

Ubuntu 10.04 LTS:
python3.1-minimal 3.1.2-0ubuntu3.1

In general, a standard system update will make all the necessary changes. Daemons using the urllib or smtpd modules may also need to be restarted after a pplying this update.

Description: Multiple race conditions in smtpd.py in the smtpd module in Python 2.6, 2.7, 3.1, and 3.2 alpha allow remote attackers to cause a denial of service (daemon outage) by establishing and then immediately closing a TCP connection, leading to the accept function having an unexpected return value of None, an unexpected value of None for the address, or an ECONNABORTED, EAGAIN, or EWOULDBLOCK error, or the getpeername function having an ENOTCONN error, a related issue to CVE-2010-3492.
