CVE-2016-6290 – php: Use after free in unserialize() with Unexpected Session Deserialization
https://notcve.org/view.php?id=CVE-2016-6290
ext/session/session.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 does not properly maintain a certain hash data structure, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via vectors related to session deserialization. ext/session/session.c en PHP en versiones anteriores a 5.5.38, 5.6.x en versiones anteriores a 5.6.24 y 7.x en versiones anteriores a 7.0.9 no mantiene correctamente una determinada estructura de datos hash, lo que permite a atacantes remotos provocar una denegación de servicio (uso después de liberación) o posiblemente tener otro impacto no especificado a través de vectores relacionados con deserialización de sesión. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=3798eb6fd5dddb211b01d41495072fd9858d4e32 http://lists.apple.com/archives/security-announce/2016/Sep/msg00006.html http://openwall.com/lists/oss-security/2016/07/24/2 http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3631 http://www.securityfocus.com/bid/92097 http://www.securitytracker.com/id/1036430 https://bugs.php& • CWE-416: Use After Free •
CVE-2016-6295 – php: Use after free in SNMP with GC and unserialize()

ext/snmp/snmp.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly have unspecified other impact via crafted serialized data, a related issue to CVE-2016-5773. ext/snmp/snmp.c en PHP en versiones anteriores a 5.5.38, 5.6.x en versiones anteriores a 5.6.24 y 7.x en versiones anteriores a 7.0.9 no interactúa correctamente con la implementación no serializada y la recolección de basura, lo que permite a atacantes remotos provocar una denegación de servicio (uso después de liberación y caída de aplicación) o posiblemente tener otro impacto no especificado a través de datos serializados, un problema relacionado con CVE-2016-5773. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=cab1c3b3708eead315e033359d07049b23b147a3 http://lists.apple.com/archives/security-announce/2016/Sep/msg00006.html http://openwall.com/lists/oss-security/2016/07/24/2 http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3631 http://www.securityfocus.com/bid/92094 http://www.securitytracker.com/id/1036430 https://bugs.php& • CWE-416: Use After Free •
CVE-2016-6207 – php,gd: Integer overflow error within _gdContributionsAlloc()
https://notcve.org/view.php?id=CVE-2016-6207
Integer overflow in the _gdContributionsAlloc function in gd_interpolation.c in GD Graphics Library (aka libgd) before 2.2.3 allows remote attackers to cause a denial of service (out-of-bounds memory write or memory consumption) via unspecified vectors. Desbordamiento de entero en la función _gdContributionsAlloc en gd_interpolation.c en GD Graphics Library (también conocida como libgd) en versiones anteriores a 2.2.3 permite a atacantes remotos causar una denegación de servicio (escritura de memoria fuera de límites o consumo de memoria) a través de vectores no especificados. • http://lists.opensuse.org/opensuse-updates/2016-08/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-09/msg00078.html http://packetstormsecurity.com/files/138174/LibGD-2.2.2-Integer-Overflow-Denial-Of-Service.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3630 http://www.securityfocus.com/archive/1/539100/100/0/threaded http://www.securityfocus.com/bid/92080 http://www.securitytracker.com/id/1036535 http://www.ubuntu • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •
CVE-2016-5399 – PHP 5.5.37/5.6.23/7.0.8 - 'bzread()' Out-of-Bounds Write
https://notcve.org/view.php?id=CVE-2016-5399
The bzread function in ext/bz2/bz2.c in PHP before 5.5.38, 5.6.x before 5.6.24, and 7.x before 7.0.9 allows remote attackers to cause a denial of service (out-of-bounds write) or execute arbitrary code via a crafted bz2 archive. La función bzread en ext/bz2/bz2.c en PHP en versiones anteriores a 5.5.38, 5.6.x en versiones anteriores a 5.6.24, y 7.x en versiones anteriores a 7.0.9 permite a atacantes remotos provocar una denegación de servicio (escritura fuera de limites) o ejecutar código arbitrario a través de un archivo bz2 manipulado. A flaw was found in the way certain error conditions were handled by bzread() function in PHP. An attacker could use this flaw to upload a specially crafted bz2 archive which, when parsed via the vulnerable function, could cause the application to crash or execute arbitrary code with the permissions of the user running the PHP application. PHP versions 7.0.8, 5.6.23, and 5.5.37 suffers from an out-of-bounds write vulnerability in bzread(). • https://www.exploit-db.com/exploits/40155 http://packetstormsecurity.com/files/137998/PHP-7.0.8-5.6.23-5.5.37-bzread-OOB-Write.html http://php.net/ChangeLog-5.php http://php.net/ChangeLog-7.php http://rhn.redhat.com/errata/RHSA-2016-2598.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://seclists.org/fulldisclosure/2016/Jul/72 http://www.debian.org/security/2016/dsa-3631 http://www.openwall.com/lists/oss-security/2016/07/21/1 http:/ • CWE-390: Detection of Error Condition Without Action CWE-787: Out-of-bounds Write •
CVE-2016-5385 – PHP: sets environmental variable based on user supplied Proxy request header
https://notcve.org/view.php?id=CVE-2016-5385
PHP through 7.0.8 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect an application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, as demonstrated by (1) an application that makes a getenv('HTTP_PROXY') call or (2) a CGI configuration of PHP, aka an "httpoxy" issue. PHP hasta la versión 7.0.8 no intenta abordar los conflictos de espacio de nombres de RFC 3875 sección 4.1.18 y por lo tanto no protege aplicaciones de la presencia de datos de clientes no confiables en ambiente variable de HTTP_PROXY, lo que ppodría permitir a atacantes remotos redireccionar el tráfico HTTP saliente de una aplicación a un servidor proxy arbitrario través de una cabecera Proxy manipulada en una petición HTTP, según lo demostrado por (1) una aplicación que hace una llamada getenv('HTTP_PROXY') o (2) una configuración CGI de PHP, también conocido como problema "httpoxy". It was discovered that PHP did not properly protect against the HTTP_PROXY variable name clash. A remote attacker could possibly use this flaw to redirect HTTP requests performed by a PHP script to an attacker-controlled proxy via a malicious HTTP request. • http://lists.opensuse.org/opensuse-updates/2016-08/msg00003.html http://rhn.redhat.com/errata/RHSA-2016-1609.html http://rhn.redhat.com/errata/RHSA-2016-1610.html http://rhn.redhat.com/errata/RHSA-2016-1611.html http://rhn.redhat.com/errata/RHSA-2016-1612.html http://rhn.redhat.com/errata/RHSA-2016-1613.html http://www.debian.org/security/2016/dsa-3631 http://www.kb.cert.org/vuls/id/797896 http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html • CWE-20: Improper Input Validation CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
