Mandriva Linux Security Advisory 2013-117
Posted Apr 11, 2013
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2013-117 - 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. Additionally, python has been built against the system expat and ffi libraries, to avoid any future issues with those.

Ubuntu Security Notice USN-1616-1
Posted Oct 25, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1616-1 - 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. This issue only affected Ubuntu 10.04 LTS. 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. These issues only affected Ubuntu 10.04 LTS. Various other issues were also addressed.

Mandriva Linux Security Advisory 2012-096 - Multiple vulnerabilities has been discovered and corrected in python. The _ssl module would always disable the CBC IV attack countermeasure. 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 attack against victims visiting a listing page generated by SimpleHTTPServer, for a directory containing the crafted file. A race condition was found in the way the Python distutils module set file permissions during the creation of the.pypirc file. Various other issues were also addressed.

Red Hat Security Advisory 2012-0745-01

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0745-01 - Python is an interpreted, interactive, object-oriented programming language. A denial of service flaw was found in the implementation of associative arrays in Python. An attacker able to supply a large number of inputs to a Python 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.
