Mandriva Linux Security Advisory 2015-076

Mandriva Linux Security Advisory 2015-076 - Updated python3 packages fix security vulnerabilities. ZipExtFile.read goes into 100% CPU infinite loop on maliciously binary edited zips. 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. 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. 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. 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.
