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 •

https://notcve.org/view.php?id=CVE-2014-1912
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') •

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.
