medium Nessus Plugin ID 62677
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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. This issue only affected Ubuntu 11.04 and 11.10.
(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 update 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. This issue only affected Ubuntu 11.04 and 11.10. (CVE-2012-1150)

Serhiy Storchaka discovered that the UTF16 decoder in Python did not properly reset internal variables after error handling. An attacker could exploit this to cause a denial of service via memory corruption.
This issue did not affect Ubuntu 12.10. (CVE-2012-2135).

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.

Solution

Update the affected python3.2 and / or python3.2-minimal packages.
