CVE-2016-5773 – php: ZipArchive class Use After Free Vulnerability in PHP's GC algorithm and unserialize

https://notcve.org/view.php?id=CVE-2016-5773

php_zip.c in the zip extension in PHP before 5.5.37, 5.6.x before 5.6.23, and 7.x before 7.0.8 improperly interacts with the unserialize implementation and garbage collection, which allows remote attackers to execute arbitrary code or cause a denial of service (use-after-free and application crash) via crafted serialized data containing a ZipArchive object. php_zip.c en la extension zip en PHP en versiones anteriores a 5.5.37, 5.6.x en versiones anteriores a 5.6.23 y 7.x en versiones anteriores 7.0.8 interactúa incorrectamente con la implementación no serializada y la recolección de basura, lo que permite a atacantes remotos ejecutar un código arbitrario o provocar una denegación de servicio (uso después de liberación y caída de aplicación) a través de datos serializados manipulados que contienen un objeto ZipArchive. • http://github.com/php/php-src/commit/f6aef68089221c5ea047d4a74224ee3deead99a6?w=1 http://lists.apple.com/archives/security-announce/2016/Sep/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00004.html 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-3618 http://www.openwall.com/lists/oss-security/2016/06/23/4 http://www.securityfocus.com/bid/ • CWE-416: Use After Free •
