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 •
CVE-2014-9365 – python: failure to validate certificates in the HTTP client with TLS (PEP 476)
https://notcve.org/view.php?id=CVE-2014-9365
The HTTP clients in the (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib libraries in CPython (aka Python) 2.x before 2.7.9 and 3.x before 3.4.3, when accessing an HTTPS URL, do not (a) check the certificate against a trust store or verify that the server hostname matches a domain name in the subject's (b) Common Name or (c) subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate. Los clientes HTTP en las librarias (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib en CPython (también conocido como Python) 2.x anterior a 2.7.9 y 3.x anterior a 3.4.3, cuando accede a una URL HTTPS, not (a) comprueba el certificado contra un almacen trust o verifica que elnombre del servidor coincide con un nombre de dominio en el campo del tema (b) Common Name o (c) subjectAltName del certificado X.509, lo que permite a atacantes man-in-the-middle falsificar servidores SSL a través de un certificado válido arbitrario. 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. • http://bugs.python.org/issue22417 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://www.openwall.com/lists/oss-security/2014/12/11/1 http://www.oracle.com/technetwork/topics/security/bulletinjan2015-2370101.html http://www.oracle.com/technetwork/topics/security/bulletinoct2015-2511968.html http://www.securityfocus.com/bid/71639 https://access.redhat.com/errata/RHSA-2016:1166 https://access.redhat.com/errata/RHSA-2017:1162 https://access.redhat.com/errata • CWE-345: Insufficient Verification of Data Authenticity •
