Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Python 2.6 through 3.2 creates ~/.pypirc with world-readable permissions before changing them after data     has been written, which introduces a race condition that allows local users to obtain a username and     password by reading this file. (CVE-2011-4944)

Note that Nessus relies on the presence of the package as reported by the vendor.

It was discovered that Python would prepend an empty string to sys.path under certain circumstances. A local attacker with write access to the current working directory could exploit this to execute arbitrary code. (CVE-2008-5983)

It was discovered that the audioop module did not correctly perform input validation. If a user or automated system were tricked into opening a crafted audio file, an attacker could cause a denial of service via application crash. (CVE-2010-1634, CVE-2010-2089)

Giampaolo Rodola discovered several race conditions in the smtpd module. A remote attacker could exploit this to cause a denial of service via daemon outage. (CVE-2010-3493)

It was discovered that the CGIHTTPServer module did not properly perform input validation on certain HTTP GET requests. A remote attacker could potentially obtain access to CGI script source files.
(CVE-2011-1015)

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 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.
(CVE-2012-1150).

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.

It was discovered that the Expat module in Python 2.5 computed hash values without restricting the ability to trigger hash collisions predictably. If a user or application using pyexpat were tricked into opening a crafted XML file, an attacker could cause a denial of service by consuming excessive CPU resources. (CVE-2012-0876)

Tim Boddy discovered that the Expat module in Python 2.5 did not properly handle memory reallocation when processing XML files. If a user or application using pyexpat were tricked into opening a crafted XML file, an attacker could cause a denial of service by consuming excessive memory resources. (CVE-2012-1148).

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.

Multiple vulnerabilities has been discovered and corrected in python :

The _ssl module would always disable the CBC IV attack countermeasure (CVE-2011-3389).

A flaw was found in the way the Python SimpleHTTPServer module generated directory listings. An attacker able to upload a file with a specially crafted name to a server could possibly perform a cross-site scripting (XSS) attack against victims visiting a listing page generated by SimpleHTTPServer, for a directory containing the crafted file (if the victims were using certain web browsers) (CVE-2011-4940).

A race condition was found in the way the Python distutils module set file permissions during the creation of the .pypirc file. If a local user had access to the home directory of another user who is running distutils, they could use this flaw to gain access to that user's .pypirc file, which can contain usernames and passwords for code repositories (CVE-2011-4944).

A flaw was found in the way the Python SimpleXMLRPCServer module handled clients disconnecting prematurely. A remote attacker could use this flaw to cause excessive CPU consumption on a server using SimpleXMLRPCServer (CVE-2012-0845).

Hash table collisions CPU usage DoS for the embedded copy of expat (CVE-2012-0876).

A denial of service flaw was found in the implementation of associative arrays (dictionaries) in Python. An attacker able to supply a large number of inputs to a Python application (such as HTTP POST request parameters sent to a web application) that are used as keys when inserting data into an array could trigger multiple hash function collisions, making array operations take an excessive amount of CPU time. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions (CVE-2012-1150).

The updated packages have been patched to correct these issues.

a. VMware vSphere API denial of service vulnerability

   The VMware vSphere API contains a denial of service    vulnerability.  This issue allows an unauthenticated user to    send a maliciously crafted API request and disable the host    daemon. Exploitation of the issue would prevent management    activities on the host but any virtual machines running on the    host would be unaffected.

   VMware would like to thank Sebastian Tello of Core Security    Technologies for reporting this issue to us.

Updated python packages fix security vulnerabilities :

A race condition was found in the way the Python distutils module set file permissions during the creation of the .pypirc file. If a local user had access to the home directory of another user who is running distutils, they could use this flaw to gain access to that user's .pypirc file, which can contain usernames and passwords for code repositories (CVE-2011-4944).

Additionally, python has been built against the system expat and ffi libraries, to avoid any future issues with those (mitigates CVE-2012-0876 for expat).

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2012-663:02 advisory.

    Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl,     Scheme or Java. Python includes modules, classes, exceptions, very high level dynamic data types and     dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various     windowing systems (X11, Motif, Tk, Mac and MFC).
    Programmers can write new built-in modules for Python in C or C++. Python can be used as an extension     language for applications that need a programmable interface. This package contains most of the standard     Python modules, as well as modules for interfacing to the Tix widget set for Tk and RPM.
    Note that documentation for Python is provided in the python-docs package.
    Security issues fixed with this release:
    CVE-2011-4940     The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x     before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP     header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against     Internet Explorer 7 via UTF-7 encoding.
    CVE-2011-4944     CVE-2012-0845     CVE-2012-1150     No description available at the time of writing, please use the CVE links below.
