https://notcve.org/view.php?id=CVE-2013-7040
Python 2.7 before 3.4 only uses the last eight bits of the prefix to randomize hash values, which causes it to compute hash values without restricting the ability to trigger hash collisions predictably and makes it easier for context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1150. Python 2.7 anterior a 3.4 solamente utiliza las últimas ocho partes del prefijo para asignar valores de hash de forma aleatoria, lo que causa que calcule valores de hash sin restringir la habilidad de provocar colisiones de hash de forma previsible y facilita a atacantes dependientes de contexto causar una denegación de servicio (consumo de CPU) a través de entradas manipuladas hacia una aplicación que mantiene una tabla de hash. NOTA: esta vulnerabilidad existe debido a una solución incompleta para CVE-2012-1150. • http://bugs.python.org/issue14621 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://www.openwall.com/lists/oss-security/2013/12/09/13 http://www.openwall.com/lists/oss-security/2013/12/09/3 http://www.securityfocus.com/bid/64194 https://support.apple.com/kb/HT205031 • CWE-310: Cryptographic Issues •

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. Desbordamiento de buffer en la función socket.recvfrom_into en Modules/socketmodule.c en Python 2.5 anterior a 2.7.7, 3.x anterior a 3.3.4 y 3.4.x anterior a 3.4rc1 permite a atacantes remotos ejecutar código arbitrario a través de una cadena manipulada. 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. • https://www.exploit-db.com/exploits/31875 http://bugs.python.org/issue20246 http://hg.python.org/cpython/rev/87673659d8f7 http://lists.apple.com/archives/security-announce/2015/Aug/msg00001.html http://lists.opensuse.org/opensuse-updates/2014-04/msg00035.html http://lists.opensuse.org/opensuse-updates/2014-05/msg00008.html http://pastebin.com/raw.php?i=GHXSmNEg http://rhn.redhat.com/errata/RHSA-2015-1064.html http://rhn.redhat.com/errata/RHSA-2015-1330.html http://www&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2013-2099
Algorithmic complexity vulnerability in the ssl.match_hostname function in Python 3.2.x, 3.3.x, and earlier, and unspecified versions of python-backports-ssl_match_hostname as used for older Python versions, allows remote attackers to cause a denial of service (CPU consumption) via multiple wildcard characters in the common name in a certificate. Vulnerabilidad de la complejidad algorítmica en la función ssl.match_hostname en Python 3.2.x, 3.3.x, y anteriores, y las versiones no especificadas de python-backports-ssl_match_hostname como las usadas por versiones anteriores de Python, permite a atacantes remotos provocar una denegación de servicio (consumo de CPU ) a través de múltiples caracteres comodín en el nombre común en el certificado. A denial of service flaw was found in the way Python's SSL module implementation performed matching of certain certificate names. A remote attacker able to obtain a valid certificate that contained multiple wildcard characters could use this flaw to issue a request to validate such a certificate, resulting in excessive consumption of CPU. • http://bugs.python.org/issue17980 http://rhn.redhat.com/errata/RHSA-2014-1690.html http://secunia.com/advisories/55107 http://secunia.com/advisories/55116 http://www.openwall.com/lists/oss-security/2013/05/16/6 http://www.ubuntu.com/usn/USN-1983-1 http://www.ubuntu.com/usn/USN-1984-1 http://www.ubuntu.com/usn/USN-1985-1 https://access.redhat.com/errata/RHSA-2016:1166 https://bugzilla.redhat.com/show_bug.cgi?id=963260 https://access.redhat.com/ • CWE-399: Resource Management Errors CWE-407: Inefficient Algorithmic Complexity •

The ssl.match_hostname function in the SSL module in Python 2.6 through 3.4 does not properly handle a '\0' character in a domain name in the Subject Alternative Name field of an X.509 certificate, which allows man-in-the-middle attackers to spoof arbitrary SSL servers via a crafted certificate issued by a legitimate Certification Authority, a related issue to CVE-2009-2408. La función ssl.match_hostname en el módulo SSL en Python v2.6 hasta v3.4 no manejar adecuadamente un carácter “\0” en un nombre de dominio en el campo Subject Alternative Name de un certificado X.509, lo que permite a atacantes "man-in-the-middle" suplantar servidores SSL de su elección mediante un certificado manipulado expedido por una Autoridad Certificadora legítima, un problema relacionado con CVE-2009-2408 • http://bugs.python.org/issue18709 http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00026.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00027.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00028.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00029.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00042.html http://lists.opensuse.org/opensuse-updates/2013-09/msg00043.html • CWE-20: Improper Input Validation •
