Ubuntu Security Notice 1592-1 - Niels Heinen discovered that the urllib and urllib2 modules would process Location headers that specify a redirection to file: URLs. A remote attacker could exploit this to obtain sensitive information or cause a denial of service. This issue only affected Ubuntu 11.04. It was discovered that SimpleHTTPServer did not use a charset parameter in the Content-Type HTTP header. An attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 users. This issue only affected Ubuntu 11.04. Various other issues were also addressed.

python2.7 vulnerabilities
============================================================================

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

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

Several security issues were fixed in Python 2.7.

Software Description:
- python2.7: An interactive high-level object-oriented language
(version 2.7)

Details:

Niels Heinen discovered that the urllib and urllib2 modules would
process Location headers that specify a redirection to file: URLs. A
remote attacker could exploit this to obtain sensitive information or
cause a denial of service. This issue only affected Ubuntu 11.04.
(CVE-2011-1521)

It was discovered that SimpleHTTPServer did not use a charset parameter
in the Content-Type HTTP header. An attacker could potentially exploit
this to conduct cross-site scripting (XSS) attacks against Internet
Explorer 7 users. This issue only affected Ubuntu 11.04. (CVE-2011-4940)

It was discovered that Python distutils contained a race condition when
creating the ~/.pypirc file. A local attacker could exploit this to
obtain sensitive information. (CVE-2011-4944)

It was discovered that SimpleXMLRPCServer did not properly validate its
input when handling HTTP POST requests. A remote attacker could exploit
this to cause a denial of service via excessive CPU utilization.
(CVE-2012-0845)

It was discovered that Python was susceptible to hash algorithm attacks.
An attacker could cause a denial of service under certian circumstances.
This updates adds the '-R' command line option and honors setting the
PYTHONHASHSEED environment variable to 'random' to salt str and datetime
objects with an unpredictable value. (CVE-2012-1150)

Update instructions:

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

Ubuntu 11.10:
python2.7 2.7.2-5ubuntu1.1
python2.7-minimal 2.7.2-5ubuntu1.1

Ubuntu 11.04:
python2.7 2.7.1-5ubuntu2.2
