CVE-2014-7185

TITLE

Python of bufferobject.c Integer overflow vulnerability

DESCRIPTION

Integer overflow in bufferobject.c in Python before 2.7.8 allows context-dependent attackers to obtain sensitive information from process memory via a large size and offset in a "buffer" function. Python is prone to an integer-overflow vulnerability because it fails to properly bounds check user-supplied input before copying it into an insufficiently sized buffer. Attackers can exploit this issue to obtain potentially sensitive information or cause a denial-of-service condition. Versions prior to Python 2.7.8 are vulnerable. The language is scalable, supports modules and packages, and supports multiple platforms.

A malicious ftp, http, imap, nntp, pop or smtp server could use this issue to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-7185) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: python2.7 2.7.8-10ubuntu1.1 python2.7-minimal 2.7.8-10ubuntu1.1 python3.4 3.4.2-1ubuntu0.1 python3.4-minimal 3.4.2-1ubuntu0.1 Ubuntu 14.04 LTS: python2.7 2.7.6-8ubuntu0.2 python2.7-minimal 2.7.6-8ubuntu0.2 python3.4 3.4.0-2ubuntu1.1 python3.4-minimal 3.4.0-2ubuntu1.1 Ubuntu 12.04 LTS: python2.7 2.7.3-0ubuntu3.8 python2.7-minimal 2.7.3-0ubuntu3.8 python3.2 3.2.3-0ubuntu3.7 python3.2-minimal 3.2.3-0ubuntu3.7 In general, a standard system update will make all the necessary changes. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: python27 security, bug fix, and enhancement update Advisory ID: RHSA-2015:1064-01 Product: Red Hat Software Collections Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-1064.html Issue date: 2015-06-04 CVE Names: CVE-2013-1752 CVE-2013-1753 CVE-2014-1912 CVE-2014-4616 CVE-2014-4650 CVE-2014-7185 ===================================================================== 1. Summary: Updated python27 collection packages that fix multiple security issues and several bugs are now available as part of Red Hat Software Collections 2. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.5) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 3. Description: 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. (BZ#1167912) The following security issues were fixed in the python27-python component: 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. (CVE-2014-1912) It was discovered that the Python xmlrpclib module did not restrict the size of gzip-compressed HTTP responses. A malicious XMLRPC server could cause an XMLRPC client using xmlrpclib to consume an excessive amount of memory. (CVE-2013-1753) It was discovered that multiple Python standard library modules implementing network protocols (such as httplib or smtplib) failed to restrict the sizes of server responses. A malicious server could cause a client using one of the affected modules to consume an excessive amount of memory. (CVE-2013-1752) It was discovered that the CGIHTTPServer module incorrectly handled URL encoded paths. A remote attacker could use this flaw to execute scripts outside of the cgi-bin directory, or disclose the source code of the scripts in the cgi-bin directory. An attacker able to control these arguments could use this flaw to disclose portions of the application memory or cause it to crash. (CVE-2014-7185) The following security issue was fixed in the python27-python and python27-python-simplejson components: A flaw was found in the way the json module handled negative index arguments passed to certain functions (such as raw_decode()). An attacker able to control the index value passed to one of the affected functions could possibly use this flaw to disclose portions of the application memory. (CVE-2014-4616) In addition, this update adds the following enhancement: * The python27 Software Collection now includes the python-wheel and python-pip modules. (BZ#994189, BZ#1167902) All python27 users are advised to upgrade to these updated packages, which correct these issues and add these enhancements. All running python27 instances must be restarted for this update to take effect. 4.

Python supports interfaces to many system calls and libraries, as well as to various windowing systems (X11, Motif, Tk, Mac and MFC). Space precludes documenting all of these changes in this advisory. 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). 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 (CVE-2013-1752). Denial of service flaws due to unbound readline() calls in the imaplib, poplib, and smtplib modules (CVE-2013-1752). A gzip bomb and unbound read denial of service flaw in python XMLRPC library (CVE-2013-1753). 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. Python before 2.7.8 is vulnerable to an integer overflow in the buffer type (CVE-2014-7185). When Python&#039;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 (CVE-2014-9365). The python-pip and tix packages was added due to missing build dependencies. The verification of md5 checksums and GPG signatures is performed automatically for you.
