CVE-2014-1912

Status Candidate

Overview

Buffer overflow in the socket.recvfrom_into function in Modules/socketmodule.c in Python 2.5 before 2.7.7, 3.x before 3.3.4, and 3.4.x before 3.4rc1 allows remote attackers to execute arbitrary code via a crafted string.

Red Hat Security Advisory 2015-1330-01

Red Hat Security Advisory 2015-1330-01 - Python is an interpreted, interactive, object-oriented programming language often compared to Tcl, Perl, Scheme, or Java. Python includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. It was discovered that the socket.recvfrom_into() function failed to check the size of the supplied buffer. This could lead to a buffer overflow when the function was called with an insufficiently sized buffer.

Red Hat Security Advisory 2015-1064-01 - Python is an interpreted, interactive, object-oriented programming language that supports modules, classes, exceptions, high-level dynamic data types, and dynamic typing. The python27 collection provide a stable release of Python 2.7 with a number of additional utilities and database connectors for MySQL and PostgreSQL. The python27-python packages have been upgraded to upstream version 2.7.8, which provides numerous bug fixes over the previous version.

Mandriva Linux Security Advisory 2015-076
Posted Mar 27, 2015

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.

Mandriva Linux Security Advisory 2015-075 - 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. This updates the python package to version 2.7.6, which fixes several other bugs, including denial of service flaws due to unbound readline() calls in the ftplib and nntplib modules. Denial of service flaws due to unbound readline() calls in the imaplib, poplib, and smtplib modules. A gzip bomb and unbound read denial of service flaw in python XMLRPC library. 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. Python before 2.7.8 is vulnerable to an integer overflow in the buffer type. When Python's standard library HTTP clients (httplib, urllib, urllib2, xmlrpclib) are used to access resources with HTTPS, by default the certificate is not checked against any trust store, nor is the hostname in the certificate checked against the requested host. It was possible to configure a trust root to be checked against, however there were no faculties for hostname checking. The python-pip and tix packages was added due to missing build dependencies.
