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. 7) - noarch, x86_64 3. 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. (CVE-2014-4616) In addition, this update adds the following enhancement: * The python27 Software Collection now includes the python-wheel and python-pip modules. All running python27 instances must be restarted for this update to take effect. 6) - i386, x86_64 3. Space precludes documenting all of these changes in this advisory. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: python security, bug fix, and enhancement update Advisory ID: RHSA-2015:2101-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2101.html Issue date: 2015-11-19 CVE Names: CVE-2013-1752 CVE-2013-1753 CVE-2014-4616 CVE-2014-4650 CVE-2014-7185 ===================================================================== 1.

Description: 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 (X11, Motif, Tk, Mac and MFC). 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) 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) The Python standard library HTTP client modules (such as httplib or urllib) did not perform verification of TLS/SSL certificates when connecting to HTTPS servers. A man-in-the-middle attacker could use this flaw to hijack connections and eavesdrop or modify transferred data. (CVE-2014-9365) Note: The Python standard library was updated to make it possible to enable certificate verification by default. However, for backwards compatibility, verification remains disabled by default. Future updates may change this default. Refer to the Knowledgebase article 2039753 linked to in the References section for further details about this change. (BZ#1219108) This update also fixes the following bugs: * Subprocesses used with the Eventlet library or regular threads previously tried to close epoll file descriptors twice, which led to an "Invalid argument" error. Subprocesses have been fixed to close the file descriptors only once. (BZ#1103452) * When importing the readline module from a Python script, Python no longer produces erroneous random characters on stdout. (BZ#1189301) * The cProfile utility has been fixed to print all values that the "-s" option supports when this option is used without a correct value. (BZ#1237107) * The load_cert_chain() function now accepts "None" as a keyfile argument. (BZ#1250611) In addition, this update adds the following enhancements: * Security enhancements as described in PEP 466 have been backported to the Python standard library, for example, new features of the ssl module: Server Name Indication (SNI) support, support for new TLSv1.x protocols, new hash algorithms in the hashlib module, and many more. (BZ#1111461) * Support for the ssl.PROTOCOL_TLSv1_2 protocol has been added to the ssl library. (BZ#1192015) * The ssl.SSLSocket.version() method is now available to access information about the version of the SSL protocol used in a connection. (BZ#1259421) All python users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. 4.
