CVE-2013-7440 – python: wildcard matching rules do not follow RFC 6125
https://notcve.org/view.php?id=CVE-2013-7440
The ssl.match_hostname function in CPython (aka Python) before 2.7.9 and 3.x before 3.3.3 does not properly handle wildcards in hostnames, which might allow man-in-the-middle attackers to spoof servers via a crafted certificate. La función ssl.match_hostname en CPython (también concida como Python) en versiones anteriores a 2.7.9 y 3.x en versiones anteriores a 3.3.3 no maneja correctamente comodines en los nombres de host, lo que podría permitir a atacantes man-in-the-middle suplantar servidores a través de un certificado manipulado. Multiple flaws were found in the way Python's SSL module performed matching of certificate names containing wildcards. A remote attacker able to obtain a valid certificate that contained certain names with wildcards could have them incorrectly accepted by Python SSL clients, not following the RFC 6125 recommendations. • http://seclists.org/oss-sec/2015/q2/483 http://seclists.org/oss-sec/2015/q2/523 http://www.securityfocus.com/bid/74707 https://access.redhat.com/errata/RHSA-2016:1166 https://bugs.python.org/issue17997 https://bugzilla.redhat.com/show_bug.cgi?id=1224999 https://hg.python.org/cpython/rev/10d0edadbcdd https://access.redhat.com/security/cve/CVE-2013-7440 • CWE-19: Data Processing Errors •
CVE-2016-0718 – expat: Out-of-bounds heap read on crafted input causing crash
https://notcve.org/view.php?id=CVE-2016-0718
Expat allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a malformed input document, which triggers a buffer overflow. Expat permite a atacantes dependientes del contexto provocar una denegación de servicio (caída) o posiblemente ejecutar código arbitrario a través de un documento de entrada mal formado, lo que desencadena un desbordamiento de buffer. An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. • http://lists.apple.com/archives/security-announce/2016/Jul/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-125: Out-of-bounds Read •

CVE-2015-1283 – chromium-browser: Heap-buffer-overflow in expat.
https://notcve.org/view.php?id=CVE-2015-1283
Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716. Múltiples vulnerabilidades de desbordamiento de entero en la función XML_GetBuffer en Expat hasta la versión 2.1.0 implementada en Chrome en versiones anteriores a la 44.0.2403.89 y otros productos permite a atacantes remotos causar una denegación de servicio mediante un desbordamiento de buffer basado en memoria dinámica o, posiblemente tener otro impacto no especificado a través de datos XML manipulados, un tema relacionado con CVE-2015-2716. • http://googlechromereleases.blogspot.com/2015/07/stable-channel-update_21.html http://lists.opensuse.org/opensuse-security-announce/2015-07/msg00038.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00010.html http://rhn.redhat.com/errata/RHSA-2015-1499.html http • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
CVE-2013-1753 – python: XMLRPC library unrestricted decompression of HTTP responses using gzip enconding
https://notcve.org/view.php?id=CVE-2013-1753
The gzip_decode function in the xmlrpc client library in Python 3.4 and earlier allows remote attackers to cause a denial of service (memory consumption) via a crafted HTTP request. La función gzip_decode en la biblioteca de cliente xmlrpc en Python versiones 3.4 y anteriores, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) por medio de una petición HTTP especialmente diseñada. It was discovered that the Python xmlrpclib did not restrict the size of a gzip compressed HTTP responses. A malicious XMLRPC server could cause an XMLRPC client using xmlrpclib to consume an excessive amount of memory. • https://bugs.python.org/issue16043 https://access.redhat.com/security/cve/CVE-2013-1753 https://bugzilla.redhat.com/show_bug.cgi?id=1046170 • CWE-400: Uncontrolled Resource Consumption •
