QuickTime in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted AVI file. QuickTime en Apple Mac OS X v10.6.x anterior v10.6.5 permite a atacantes remotos ejecutar código de su elección o causar una denegación de servicio (corrupción de memoria y caída de aplicación) a través de un fichero AVI manipulado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the code responsible for parsing rec chunks within an AVI media file. By modifying specific values within the data structure a heap corruption condition can be triggered. • http://lists.apple.com/archives/security-announce/2010//Dec/msg00000.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://support.apple.com/kb/HT4435 http://support.apple.com/kb/HT4447 http://www.securitytracker.com/id?1024729 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

QuickTime in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Sorenson movie file. QuickTime en Apple Mac OS X v10.6.x anteriores a v10.6.5 permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servicio (corrupción de memoria y caída de la aplicación) a través de una fichero de vídeo en formato Sorenson manipulado. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple's Quicktime. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the way QuickTime decompresses video samples that are encoded with the Sorenson v3 Codec. Upon parsing malformed video sample data, the application will calculate an index for decompression and use that to seek into a buffer used for writing. • http://lists.apple.com/archives/security-announce/2010//Dec/msg00000.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://support.apple.com/kb/HT4435 http://support.apple.com/kb/HT4447 http://www.securitytracker.com/id?1024729 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Buffer overflow in QuickTime in Apple Mac OS X 10.6.x before 10.6.5 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG movie file. Desbordamiento de búfer basado en pila en QuickTime en Apple Mac OS X v10.6.x anterior a v10.6.5 permite a atacantes remotos ejecutar código de su elección o provocar una denegación de servivio (caída de la aplicación) a través de un archivo de película MPEG maniuplado This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Quicktime. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The flaw exists within the QuickTimeMPEG.qtx module. When handling an ELST atom's edit list table data large values are not handled properly. Specifically, the media rate field is explicitly trusted and can be abused to control memory copy operations. • http://lists.apple.com/archives/security-announce/2010//Dec/msg00000.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://support.apple.com/kb/HT4435 http://support.apple.com/kb/HT4447 http://www.securitytracker.com/id?1024729 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Networking in Apple Mac OS X 10.6.2 through 10.6.4 allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted PIM packet. Networking en Apple Mac OS X v10.6.2 hasta v10.6.4 permite a atacantes remotos causar una denegación de servicio (desreferencia de puntero nulo y caída de sistema) a través de un paquete PIM manipulado. This vulnerability allows remote attackers to denial of service the IPv6 stack of an installation of Apple Mac OSX. No authentication or user interaction is required in order to exploit this vulnerability. The specific flaw exists within OSX's IPv6 stack. A NULL pointer dereference vulnerability was discovered in the xnu kernel implementation when a specially formatted packet is sent to it. • http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.apple.com/archives/security-announce/2010//Nov/msg00003.html http://secunia.com/advisories/42314 http://support.apple.com/kb/HT4435 http://support.apple.com/kb/HT4456 http://www.securitytracker.com/id?1024723 http://www.vupen.com/english/advisories/2010/3046 • CWE-20: Improper Input Validation •
