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:/&#x • CWE-390: Detection of Error Condition Without Action CWE-787: Out-of-bounds Write •

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') •

The gdImageCropThreshold function in gd_crop.c in the GD Graphics Library (aka libgd) before 2.2.3, as used in PHP before 7.0.9, allows remote attackers to cause a denial of service (application crash) via an invalid color index. La función gdImageCropThreshold en gd_crop.c en la GD Graphics Library (también conocido como libgd) en versiones anteriores a 2.2.3, como se utiliza en PHP en versiones anteriores a 7.0.9, permite a atacantes remotos provocar una denegación de servicio (caída de aplicación) a través de un índice de color invalido. It was found that libgd did not properly handle invalid color indexes in GD files. An attacker who could submit a crafted GD file for conversion could cause applications using libgd to crash, leading to denial of service. • http://lists.opensuse.org/opensuse-updates/2016-08/msg00086.html http://lists.opensuse.org/opensuse-updates/2016-09/msg00078.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.debian.org/security/2016/dsa-3619 http://www.openwall.com/lists/oss-security/2016/06/30/1 http://www.securityfocus.com/bid/91509 http://www.securitytracker.com/id/1036276 http://www.ubuntu.com/usn/USN-3030-1 https://bugs.php.net/72494 https://github.com/libgd/libgd/commi • CWE-20: Improper Input Validation •

Multiple integer overflows in mcrypt.c in the mcrypt extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 allow remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted length value, related to the (1) mcrypt_generic and (2) mdecrypt_generic functions.
