CVE-2016-3705 – libxml2: stack overflow before detecting invalid XML file
https://notcve.org/view.php?id=CVE-2016-3705
The (1) xmlParserEntityCheck and (2) xmlParseAttValueComplex functions in parser.c in libxml2 2.9.3 do not properly keep track of the recursion depth, which allows context-dependent attackers to cause a denial of service (stack consumption and application crash) via a crafted XML document containing a large number of nested entity references. Las funciones (1) xmlParserEntityCheck y (2) xmlParseAttValueComplex en parser.c en libxml2 2.9.3 no hace seguimiento de manera adecuada de la profundidad de recursividad, lo que permite a atacantes dependientes del contexto provocar una denegación de servicio (consumo de pila y caída de la aplicación) a través de un documento XML manipulado que contiene un gran número de referencias de entidades anidadas. Missing incrementation of recursion depth counter were found in the xmlParserEntityCheck() and xmlParseAttValueComplex() functions used for parsing XML data. An attacker could launch a Denial of Service attack by passing specially crafted XML data to an application, forcing it to crash due to stack exhaustion. • http://lists.opensuse.org/opensuse-updates/2016-05/msg00055.html http://lists.opensuse.org/opensuse-updates/2016-05/msg00127.html http://rhn.redhat.com/errata/RHSA-2016-2957.html http://seclists.org/fulldisclosure/2016/May/10 http://www.oracle.com/technetwork/topics/security/bulletinjul2016-3090568.html http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http://www.securityfocus.com/bid/89854& • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
