NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-2653-1.NASL description It was discovered that multiple Python protocol libraries incorrectly limited certain data when connecting to servers. A malicious ftp, http, imap, nntp, pop or smtp server could use this issue to cause a denial of service. (CVE-2013-1752) It was discovered that the Python xmlrpc library did not limit unpacking gzip-compressed HTTP bodies. A malicious server could use this issue to cause a denial of service. (CVE-2013-1753) It was discovered that the Python json module incorrectly handled a certain argument. An attacker could possibly use this issue to read arbitrary memory and expose sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4616) It was discovered that the Python CGIHTTPServer incorrectly handled URL-encoded path separators in URLs. A remote attacker could use this issue to expose sensitive information, or possibly execute arbitrary code. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-4650) It was discovered that Python incorrectly handled sizes and offsets in buffer functions. An attacker could possibly use this issue to read arbitrary memory and obtain sensitive information. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-7185). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues. last seen 2020-03-18 modified 2015-06-26 plugin id 84428 published 2015-06-26 reporter Ubuntu Security Notice (C) 2015-2020 Canonical, Inc. / NASL script (C) 2015-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/84428 title Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : python2.7, python3.2, python3.4 vulnerabilities (USN-2653-1) NASL family SuSE Local Security Checks NASL id OPENSUSE-2014-213.NASL description Python was updated to 2.7.6 to fix bugs and security issues : - bugfix-only release - SSL-related fixes - upstream fix for CVE-2013-4238 - upstream fixes for CVE-2013-1752 - added patches for CVE-2013-1752 (bnc#856836) issues that are missing in 2.7.6: python-2.7.6-imaplib.patch python-2.7.6-poplib.patch smtplib_maxline-2.7.patch - CVE-2013-1753 (bnc#856835) gzip decompression bomb in xmlrpc client: xmlrpc_gzip_27.patch - python-2.7.6-bdist-rpm.patch: fix broken last seen 2020-06-05 modified 2014-06-13 plugin id 75294 published 2014-06-13 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/75294 title openSUSE Security Update : python (openSUSE-SU-2014:0380-1) NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2015-2101.NASL description From Red Hat Security Advisory 2015:2101 : Updated python packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 7. 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. 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. (CVE-2014-4650) An integer overflow flaw was found in the way the buffer() function handled its offset and size arguments. 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.
