Python before 2.6.8, 2.7.x before 2.7.3, 3.x before 3.1.5, and 3.2.x before 3.2.3 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. Python anteriores a v2.6.8, v2.7.x anteriores a v2.7.3, 3.x anteriores a v3.1.5, y v3.2.x anteriores a v3.2.3 procesa los valores hash sin restringir la disponibilidad para provocar colisiones predecibles, lo que permite a atacantes dependiendo del contexto provocar una denegación de servicio (consumo de CPU) a través de una entrada manipulada sobre una aplicación que mantiene una tabla hash. • http://bugs.python.org/issue13703 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00040.html http://mail.python.org/pipermail/python-dev/2011-December/115116.html http://mail.python.org/pipermail/python-dev/2012-January/115892.html http://python.org/download/releases/2.6.8 http://python.org/download/releases/2.7.3 http://python.org/download/releases/3.1.5 http://python.org/download/ • CWE-310: Cryptographic Issues •

https://notcve.org/view.php?id=CVE-2011-4940
The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 via UTF-7 encoding. La función list_directory en lib/SimpleHTTPServer.py en SimpleHTTPServer en Python anterior a v2.5.6c1, v2.6.x anterior a v2.6.7 RC2, y v2.7.x anterior a v2.7.2 no pone un parámetro charset en la cabecera Content-Type de HTTP, lo que hace más fácil para los atacantes remotos realizar ataques XSS contra Internet Explorer 7 a través de codificación UTF-7. • http://bugs.python.org/issue11442 http://jvn.jp/en/jp/JVN51176027/index.html http://jvndb.jvn.jp/jvndb/JVNDB-2012-000063 http://secunia.com/advisories/50858 http://secunia.com/advisories/51024 http://secunia.com/advisories/51040 http://www.securityfocus.com/bid/54083 http://www.ubuntu.com/usn/USN-1592-1 http://www.ubuntu.com/usn/USN-1596-1 http://www.ubuntu.com/usn/USN-1613-1 http://www.ubuntu.com/usn/USN-1613-2 https://bugzilla.redhat.com/ • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVSS: 5.0EPSS: 0%CPEs: 22EXPL: 0CVE-2012-0876 – expat: hash table collisions CPU usage DoS
https://notcve.org/view.php?id=CVE-2012-0876
The XML parser (xmlparse.c) in expat before 2.1.0 computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML file with many identifiers with the same value. El analizador XML (xmlparse.c) en expat antes de v2.1.0 calcula los valores de hash sin restringir la capacidad de desencadenar colisiones hash de forma predecible, lo que permite causar una denegación de servicio (por consumo de CPU) a atacantes dependientes de contexto a través de un archivo XML con muchos identificadores con el mismo valor. A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. • http://bugs.python.org/issue13703#msg151870 http://lists.apple.com/archives/security-announce/2013/Oct/msg00004.html http://lists.apple.com/archives/security-announce/2015/Dec/msg00005.html http://mail.libexpat.org/pipermail/expat-discuss/2012-March/002768.html http://rhn.redhat.com/errata/RHSA-2012-0731.html http://rhn.redhat.com/errata/RHSA-2016-0062.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://secunia.com/advisories/49504 http://secunia.com/advisories/51024 • CWE-400: Uncontrolled Resource Consumption CWE-407: Inefficient Algorithmic Complexity •

The urllib and urllib2 modules in Python 2.x before 2.7.2 and 3.x before 3.2.1 process Location headers that specify redirection to file: URLs, which makes it easier for remote attackers to obtain sensitive information or cause a denial of service (resource consumption) via a crafted URL, as demonstrated by the file:///etc/passwd and file:///dev/zero URLs.
