CVE-2011-4885 – PHP 5.3.8 - Hashtables Denial of Service
https://notcve.org/view.php?id=CVE-2011-4885
PHP before 5.3.9 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters. PHP anterior a v5.3.9 calcula los valores hash de los parámetros de forma, sin restringir la capacidad de desencadenar colisiones hash predecible, lo que permite a atacantes remotos provocar una denegación de servicio (consumo de CPU) mediante el envío de gran cantidad de parámetros a mano. • https://www.exploit-db.com/exploits/18296 https://www.exploit-db.com/exploits/18305 https://www.exploit-db.com/exploits/2012 http://archives.neohapsis.com/archives/bugtraq/2011-12/0181.html http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 http://lists.apple.com/archives/security-announce/2012/May/msg00001.html http://lists.opensuse.org/opensuse-security-announce/2012-03/msg00013.html http://lists.opensuse.org/opensuse-security-announce/2012-03/msg00016.html ht • CWE-20: Improper Input Validation •
CVE-2011-3268
https://notcve.org/view.php?id=CVE-2011-3268
Buffer overflow in the crypt function in PHP before 5.3.7 allows context-dependent attackers to have an unspecified impact via a long salt argument, a different vulnerability than CVE-2011-2483. Desbordamiento de búfer en la función de cifrado en PHP antes de v5.3.7, permite a atacantes dependientes de contexto tener un impacto no especificado a través de un argumento "long salt", una vulnerabilidad diferente a CVE-2011-2483. • http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://osvdb.org/74738 http://support.apple.com/kb/HT5130 http://svn.php.net/viewvc/php/php-src/branches/PHP_5_3/ext/standard/php_crypt_r.c?r1=311300&r2=311390&pathrev=315218 http://www.mandriva.com/security/advisories?name=MDVSA-2011:165 http://www.php.net/ChangeLog-5.php#5.3.7 http://www.php.net/archive/2011.php#id2011-08-18-1 http://www.securityfocus.com/bid/49241 https://exch • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2011-3267
https://notcve.org/view.php?id=CVE-2011-3267

CVE-2011-3182 – PHP < 5.3.7 - Multiple Null Pointer Dereference Denial of Service Vulnerabilities
https://notcve.org/view.php?id=CVE-2011-3182
PHP before 5.3.7 does not properly check the return values of the malloc, calloc, and realloc library functions, which allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) or trigger a buffer overflow by leveraging the ability to provide an arbitrary value for a function argument, related to (1) ext/curl/interface.c, (2) ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4) ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6) ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8) ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10) TSRM/tsrm_win32.c, and (11) the strtotime function. PHP anterior a 5.3.7 no comprueba correctamente valores de retorno en las funciones malloc, calloc, y realloc, lo que permite a atacantes dependientes del contexto provocar una denegación de servicio (desreferenciar un puntero NULL y caída de la aplicación) o provocar un desbordamiento de búfer elevando la abilidad de proporcionar un valor de su elección para un argumento de una función, relacionado con (1) ext/curl/interface.c, (2) ext/date/lib/parse_date.c, (3) ext/date/lib/parse_iso_intervals.c, (4) ext/date/lib/parse_tz.c, (5) ext/date/lib/timelib.c, (6) ext/pdo_odbc/pdo_odbc.c, (7) ext/reflection/php_reflection.c, (8) ext/soap/php_sdl.c, (9) ext/xmlrpc/libxmlrpc/base64.c, (10) TSRM/tsrm_win32.c, y (11) la función strtotime. • https://www.exploit-db.com/exploits/36070 http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://marc.info/?l=full-disclosure&m=131373057621672&w=2 http://securityreason.com/achievement_securityalert/101 http://support.apple.com/kb/HT5130 http://www.mandriva.com/security/advisories?name=MDVSA-2011:165 http://www.openwall.com/lists/oss-security/2011/08/22/9 http://www.securityfocus.com/bid/49249 https://exchange.xforce.ibmcloud.com/vulnerabilities/69430 •
CVE-2011-2483 – crypt_blowfish: 8-bit character mishandling allows different password pairs to produce the same hash
https://notcve.org/view.php?id=CVE-2011-2483
crypt_blowfish before 1.1, as used in PHP before 5.3.7 on certain platforms, PostgreSQL before 8.4.9, and other products, does not properly handle 8-bit characters, which makes it easier for context-dependent attackers to determine a cleartext password by leveraging knowledge of a password hash. crypt_blowfish en versiones anteriores a 1.1, como se utiliza en PHP en versiones anteriores a 5.3.7 en ciertas plataformas, PostgreSQL en versiones anteriores a 8.4.9 y otros productos, no maneja adecuadamente caracteres de 8-bit, lo que hace más fácil a atacantes dependientes de contexto determinar una contraseña en texto plano aprovechando el conocimiento del hash de una contraseña. • http://freshmeat.net/projects/crypt_blowfish http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 http://lists.apple.com/archives/security-announce/2012/Feb/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2011-08/msg00015.html http://php.net/security/crypt_blowfish http://support.apple.com/kb/HT5130 http://www.debian.org/security/2011/dsa-2340 http://www.debian.org/security/2012/dsa-2399 http://www.mandriva.com/security/advisories?name=MDVSA-2011:165 • CWE-310: Cryptographic Issues •
