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 •

https://notcve.org/view.php?id=CVE-2011-1521
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. Los módulos urllib y urllib2 en Python v2.x anteriores a v2.7.2 y v3.x anteriores a v3.2.1 procesan los encabezados de ubicación que especificar la redirección del fichero: URLs, lo que hace que sea más fácil para los atacantes remotos obtener información sensible o provocar una denegación de servicio (consumo de recursos) a través de una URL manipulada, como lo demuestra lso ficheros URLs: //etc/passwd y //dev/zero. • http://bugs.python.org/issue11662 http://hg.python.org/cpython/file/96a6c128822b/Misc/NEWS http://hg.python.org/cpython/file/b2934d98dac1/Misc/NEWS http://hg.python.org/cpython/rev/96a6c128822b http://hg.python.org/cpython/rev/b2934d98dac1 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2011-05/msg00005.html http://openwall.com/lists/oss-security/2011/03/24/5 http://openwall.com/lists/oss-secur • CWE-399: Resource Management Errors •

The asyncore module in Python before 3.2 does not properly handle unsuccessful calls to the accept function, and does not have accompanying documentation describing how daemon applications should handle unsuccessful calls to the accept function, which makes it easier for remote attackers to conduct denial of service attacks that terminate these applications via network connections. El módulo asyncore en Python anterior a v3.2 no controla correctamente llamadas fallidas a la función accept, y no tiene la documentación adjunta que describa cómo las aplicaciones demonio atienden las llamadas sin éxito a la función accept, lo cual facilita a atacantes remotos realizar ataques de denegación de servicio que terminan estas aplicaciones a través de conexiones de red. • http://bugs.python.org/issue6706 http://www.mandriva.com/security/advisories?name=MDVSA-2010:215 http://www.mandriva.com/security/advisories?name=MDVSA-2010:216 http://www.openwall.com/lists/oss-security/2010/09/09/6 http://www.openwall.com/lists/oss-security/2010/09/11/2 http://www.openwall.com/lists/oss-security/2010/09/22/3 http://www.openwall.com/lists/oss-security/2010/09/24/3 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Ad •

Buffer underflow in the rgbimg module in Python 2.5 allows remote attackers to cause a denial of service (application crash) via a large ZSIZE value in a black-and-white (aka B/W) RGB image that triggers an invalid pointer dereference. Desbordamiento inferior de búfer en el módulo rgbimg en Python v2.5 permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un valor ZSIZE grande en una imagen RGB blanco-y-negro (también conocido como B/W) que lanza una desreferencia a un puntero no válido. • http://bugs.python.org/issue8678 http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00006.html http://secunia.com/advisories/42888 http://secunia.com/advisories/43068 http://secunia.com/advisories/43364 http://support.apple.com/kb/HT4435 http://www.mandriva.com/security/advisories?name=MDVSA-2010:215 http://www.redhat.com/support/errata/RHSA-2011-0027.html http://www.redhat.com/support/err • CWE-787: Out-of-bounds Write •
