  - reintroduce audioop.so as the problems with it seem to     be fixed (bnc#831442)

The version of MySQL Cluster running on the remote host is 7.3.x prior to 7.3.6. It is, therefore, affected by an overflow condition in the CLSTCONF component, specifically in the Python sock_recvfrom_into() function within file Modules/socketmodule.c, due to improper validation of user-supplied input when checking boundaries. An unauthenticated, remote attacker can exploit this, via a specially crafted string, to cause a denial of service condition or the execution of arbitrary code.

According to the versions of the edk2 package installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - 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.(CVE-2014-1912)

  - 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.(CVE-2014-7185)

Buffer overflow fix.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2015:1064 advisory.

    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. (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)

    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.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
