Help Viewer in Apple Mac OS X before 10.6.2 does not use an HTTPS connection to retrieve Apple Help content from a web site, which allows man-in-the-middle attackers to send a crafted help:runscript link, and thereby execute arbitrary code, via a spoofed response. Help Viewer en Apple Mac OS X anterior a v10.6.2 no utiliza una conexión HTTPS que obtiene contenido Apple Help desde una página web, lo que permite a atacantes hombre-en-el-medio (man-in-the-middle) enviar un enlace help:runscript, y de ese modo ejecutar código de su elección, a través de una respuesta suplantada. • http://lists.apple.com/archives/security-announce/2009/Nov/msg00000.html http://support.apple.com/kb/HT3937 http://www.securityfocus.com/bid/36956 http://www.vupen.com/english/advisories/2009/3184 • CWE-310: Cryptographic Issues •

Multiple use-after-free vulnerabilities in libxml2 2.5.10, 2.6.16, 2.6.26, 2.6.27, and 2.6.32, and libxml 1.8.17, allow context-dependent attackers to cause a denial of service (application crash) via crafted (1) Notation or (2) Enumeration attribute types in an XML file, as demonstrated by the Codenomicon XML fuzzing framework. Múltiples vulnerabilidades de uso anterior a la liberación en libxml2 v2.5.10, v2.6.16, v2.6.26, v2.6.27, y v2.6.32, y libxml v1.8.17, permite a atacantes dependientes de contexto producir una denegación de servicio (caída de aplicación) a través de una ,manipulación de (1) una notación o (2) tipos de atributo de enumeración en un fichero XML como se demostró en Codenomicon XML fuzzing framework. • http://googlechromereleases.blogspot.com/2009/08/stable-update-security-fixes.html http://lists.apple.com/archives/security-announce/2009/Nov/msg00000.html http://lists.apple.com/archives/security-announce/2009/Nov/msg00001.html http://lists.apple.com/archives/security-announce/2010/Jun/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2009-09/msg00001.html http://secunia.com/advisories/35036 http://secunia.com/advisories/36207 http://secunia.com/advisories/36338 http://secunia • CWE-416: Use After Free •

Stack-based buffer overflow in Image RAW in Apple Mac OS X 10.5 before 10.5.8, and 10.4 before Digital Camera RAW Compatibility Update 2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted Canon RAW image. Desbordamiento de Pila basado en búfer en Image RAW en Apple Mac OS X v10.5 anterior a v10.5.8, y v10.4 anterior a Digital Camera RAW Compatibility Update v2.6(actualización de compatibilidad con cámara digital RAW v2.6), permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (cuelgue de aplicación) a través de una imagen Canon RAW manipulada. • http://lists.apple.com/archives/security-announce/2009/Aug/msg00001.html http://osvdb.org/56843 http://secunia.com/advisories/36096 http://support.apple.com/kb/HT3757 http://www.securityfocus.com/bid/35954 http://www.securitytracker.com/id?1022674 http://www.us-cert.gov/cas/techalerts/TA09-218A.html http://www.vupen.com/english/advisories/2009/2172 https://exchange.xforce.ibmcloud.com/vulnerabilities/52423 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags. La función ippReadIO en cups/ipp.c en cupsd en CUPS antes de la versión 1.3.10 no inicia de manera apropiada la memoria para paquetes de solicitud IPP, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero nulo y caída del demonio) mediante una solicitud de programación (scheduler) con dos etiquetas IPP_TAG_UNSUPPORTED consecutivas. • https://www.exploit-db.com/exploits/33020 http://lists.apple.com/archives/security-announce/2009/Sep/msg00004.html http://lists.opensuse.org/opensuse-security-announce/2009-07/msg00002.html http://secunia.com/advisories/35322 http://secunia.com/advisories/35328 http://secunia.com/advisories/35340 http://secunia.com/advisories/35342 http://secunia.com/advisories/35685 http://secunia.com/advisories/36701 http://securitytracker.com/id?1022321 http://support.apple.com/kb/HT3865 http&# • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •

Race condition in the HFS vfs sysctl interface in XNU 1228.8.20 and earlier on Apple Mac OS X 10.5.6 and earlier allows local users to cause a denial of service (kernel memory corruption) by simultaneously executing the same HFS_SET_PKG_EXTENSIONS code path in multiple threads, which is problematic because of lack of mutex locking for an unspecified global variable. Condición de carrera en el interfaz HFS vfs sysctl en XNU v1228.8.20 y anteriores en Apple Mac OS X v10.5.6 y anteriores permite a usuarios locales producir una denegación de servicio (corrupción de la memoria del kernel) mediante la ejecucion simultanea de la ruta de código HFS_SET_PKG_EXTENSIONS en múltiples lineas de ejecución, lo cual es problemático debido a la ausencia de bloqueo de mutex para una variable inespecífica global. • https://www.exploit-db.com/exploits/8265 http://secunia.com/advisories/34424 http://www.digit-labs.org/files/exploits/xnu-vfssysctl-dos.c http://www.informationweek.com/news/hardware/mac/showArticle.jhtml?articleID=216401181 http://www.securityfocus.com/bid/34202 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
