Mandriva Linux Security Advisory MDVSA-2015:076 http://www.mandriva.com/en/support/security/ _______________________________________________________________________
Package : python3 Date : March 27, 2015 Affected: Business Server 2.0 _______________________________________________________________________
Problem Description:
Updated python3 packages fix security vulnerabilities: ZipExtFile.read goes into 100% CPU infinite loop on maliciously binary edited zips (CVE-2013-7338). A vulnerability was reported in Python's socket module, due to a boundary error within the sock_recvfrom_into() function, which could be exploited to cause a buffer overflow. This could be used to crash a Python application that uses the socket.recvfrom_info() function or, possibly, execute arbitrary code with the permissions of the user running vulnerable Python code (CVE-2014-1912). It was reported that a patch added to Python 3.2 caused a race condition where a file created could be created with world read/write permissions instead of the permissions dictated by the original umask of the process. This could allow a local attacker that could win the race to view and edit files created by a program using this call. Note that prior versions of Python, including 2.x, do not include the vulnerable _get_masked_mode() function that is used by os.makedirs() when exist_ok is set to True (CVE-2014-2667). Python are susceptible to arbitrary process memory reading by a user or adversary due to a bug in the _json module caused by insufficient bounds checking. The bug is caused by allowing the user to supply a negative value that is used an an array index, causing the scanstring function to access process memory outside of the string it is intended to access (CVE-2014-4616). The CGIHTTPServer Python module does not properly handle URL-encoded path separators in URLs. This may enable attackers to disclose a CGI script's source code or execute arbitrary scripts in the server's document root (CVE-2014-4650). _______________________________________________________________________
