The remote host is missing an update to python
announced via advisory MDVSA-2012:097.
Multiple vulnerabilities has been discovered and corrected in python:
The _ssl module would always disable the CBC IV attack countermeasure
(CVE-2011-3389).
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.
Affected: 2011.
Solution:
To upgrade automatically use MandrakeUpdate or urpmi. The verification
of md5 checksums and GPG signatures is performed automatically for you.
