Detailsinfo

A vulnerability classified as problematic was found in Apple Mac OS X up to 10.8 (Operating System). This vulnerability affects some unknown functionality of the component Python. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality. CVE summarizes:

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.

The weakness was released 10/22/2013 by Vincent Danen as APPLE-SA-2013-10-22-3 as confirmed mailinglist post (Apple Security Mailinglist). The advisory is shared for download at lists.apple.com. The mailinglist post contains:

Multiple vulnerabilities existed in python 2.6.7, the most serious of which may lead to decryption of the content of a SSL connection. This update addresses the issues by updating python to version 2.6.8 and applying the patch for CVE-2011-4944 from the Python project. Further information is available via the python site at http://www.python.org/download/releases/
This vulnerability was named CVE-2011-4944 since 12/23/2011. The exploitation appears to be difficult. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. Successful exploitation requires user interaction by the victim. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.
