Mandriva Linux Security Advisory : python3 (MDVSA-2015:076)

Synopsis :

The remote Mandriva Linux host is missing one or more security

Description :

Updated python3 packages fix security vulnerabilities : 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).
