CVSS: 9.8EPSS: 1%CPEs: 32EXPL: 0CVE-2017-12932 – php: Heap use after free in ext/standard/var_unserializer.re
https://notcve.org/view.php?id=CVE-2017-12932
ext/standard/var_unserializer.re in PHP 7.0.x through 7.0.22 and 7.1.x through 7.1.8 is prone to a heap use after free while unserializing untrusted data, related to improper use of the hash API for key deletion in a situation with an invalid array size. Exploitation of this issue can have an unspecified impact on the integrity of PHP. Ext/standard/var_unserializer.re en PHP en en sus versiones 7.0.x hasta 7.0.22 y versiones 7.1.x hasta 7.1.8 es propenso a un uso de memoria dinámica antes de liberación (heap use after free) al deserializar datos que no son de confianza. Esto está relacionado con el uso incorrecto de la API hash para borrado de claves en una situación de tamaño de array no válido. La explotación de este problema puede tener un impacto sin especificar en la integridad de PHP. • http://php.net/ChangeLog-7.php http://www.securityfocus.com/bid/100427 https://access.redhat.com/errata/RHSA-2018:1296 https://access.redhat.com/errata/RHSA-2019:2519 https://bugs.php.net/bug.php?id=74103 https://github.com/php/php-src/commit/1a23ebc1fff59bf480ca92963b36eba5c1b904c4 https://security.gentoo.org/glsa/201709-21 https://security.netapp.com/advisory/ntap-20180112-0001 https://www.debian.org/security/2018/dsa-4080 https://access.redhat.com/security/cve/CVE-2017-1 • CWE-416: Use After Free •

The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string. La función zend_string_extend en el archivo Zend/zend_string.h en PHP hasta de la versión 7.1.5 no impide cambios en los objetos de cadena que resultan en una longitud negativa, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado explotando el uso de scripts .= con una cadena larga. • http://www.securityfocus.com/bid/98518 https://bugs.php.net/bug.php?id=74577 • CWE-787: Out-of-bounds Write •

ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x before 5.6.6, when PHP-FPM is used, does not isolate each thread from libxml_disable_entity_loader changes in other threads, which allows remote attackers to conduct XML External Entity (XXE) and XML Entity Expansion (XEE) attacks via a crafted XML document, a related issue to CVE-2015-5161. ext/libxml/libxml.c en PHP en versiones anteriores a 5.5.22 y 5.6.x en versiones anteriores a 5.6.6, cuando se utiliza PHP-FPM, no aisla cada hilo de cambios libxml_disable_entity_loader en otros hilos, lo que permite a atacantes remotos llevar a cabo ataques XML External Entity (XXE) y XML Entity Expansion (XEE) a través de un documento XML manipulado, un problema relacionado con la CVE-2015-5161. • http://git.php.net/?p=php-src.git%3Ba=commit%3Bh=de31324c221c1791b26350ba106cc26bad23ace9 http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00056.html http://rhn.redhat.com/errata/RHSA-2016-2750.html http://www.openwall.com/lists/oss-security/2016/04/24/1 http://www.php.net/ChangeLog-5.php http://www.securityfocus.com/bid/ • CWE-611: Improper Restriction of XML External Entity Reference •

zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations. • ftp://patches.sgi.com/support/free/security/advisories/20060701-01-U http://archives.neohapsis.com/archives/fulldisclosure/2006-08/0166.html http://cvs.php.net/viewcvs.cgi/Zend/zend_hash.c?hideattic=0&r1=1.87.4.8.2.1&r2=1.87.4.8.2.2 http://cvs.php.net/viewcvs.cgi/Zend/zend_hash.c?hideattic=0&view=log http://rhn.redhat.com/errata/RHSA-2006-0549.html http://secunia.com/advisories/19927 http://secunia.com/advisories/21031 http://secunia.com/advisories/21050 •
