Descriptions

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.

Desbordamiento de buffer en la función socket.recvfrom_into en Modules/socketmodule.c en Python 2.5 anterior a 2.7.7, 3.x anterior a 3.3.4 y 3.4.x anterior a 3.4rc1 permite a atacantes remotos ejecutar código arbitrario a través de una cadena manipulada.

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.

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.
