Integer overflow in QuickLook, as used in Apple Mac OS X before 10.6.7 and MobileSafari in Apple iOS before 4.2.7 and 4.3.x before 4.3.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a Microsoft Office document with a crafted size field in the OfficeArtMetafileHeader, related to OfficeArtBlip, as demonstrated on the iPhone by Charlie Miller and Dion Blazakis during a Pwn2Own competition at CanSecWest 2011. Un desbordamiento de enteros en QuickLook, tal y como es usado en Mac OS X anterior a versión 10.6.7 y MobileSafari en iOS anterior a versión 4.2.7 y versiones 4.3.x anteriores a 4.3.2, de Apple, permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y bloqueo de aplicación) por medio de un documento de Microsoft Office con un campo de tamaño diseñado en OfficeArtMetafileHeader, relacionado a OfficeArtBlip, como es demostrado en el iPhone por Charlie Miller y Dion Blazakis durante una competencia de Pwn2Own en CanSecWest 2011. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Safari on the iPhone. 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 support for parsing Office files. When handling the OfficeArtMetafileHeader the process trusts the cbSize field and performs arithmetic on it before making an allocation. • http://dvlabs.tippingpoint.com/blog/2011/02/02/pwn2own-2011 http://lists.apple.com/archives/Security-announce/2011//Oct/msg00005.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00000.html http://lists.apple.com/archives/security-announce/2011//Apr/msg00001.html http://lists.apple.com/archives/security-announce/2011/Mar/msg00006.html http://secunia.com/advisories/44154 http://support.apple.com/kb/HT4581 http://support.apple.com/kb/HT4607 http://support& • CWE-189: Numeric Errors •

ipp.c in cupsd in CUPS 1.4.4 and earlier does not properly allocate memory for attribute values with invalid string data types, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted IPP request. ipp.c en cupsd en CUPS v1.4.4 y anteriores no asigna correctamente memoria para valores de atributo con tipos de datos de cadena inválidos, permitiendo a atacantes remotos provocar una denegación de servicio (uso después de liberación y caída de la aplicación) o posiblemente ejecutar código arbitrario mediante una solicitud IPP manipulada. • http://blogs.sun.com/security/entry/multiple_vulnerabilities_in_mozilla_firefox http://lists.apple.com/archives/security-announce/2010//Nov/msg00000.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/050977.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051277.html http://lists.fedoraproject.org/pipermail/package-announce/2010-November/051301.html http://lists.opensuse.org/opensuse-security-announce/2010-12/msg00000.html http://rhn.redhat.com/errata/RHSA&# • CWE-416: Use After Free •

Stack-based buffer overflow in PS Normalizer in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted PostScript document.

Heap-based buffer overflow in ImageIO in Apple Mac OS X before 10.6.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JP2 (JPEG2000) image, related to incorrect calculation and the CGImageReadGetBytesAtOffset function. Un desbordamiento de búfer en la región heap de la memoria en ImageIO en Mac OS X de Apple anterior a versión 10.6.3, permite a los atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (bloqueo de aplicación) por medio de una imagen JP2 (JPEG2000) diseñada, relacionada con un cálculo incorrecto y la función CGImageReadGetBytesAtOffset. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Mac OS X. 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 Apple ImageIO framework during the parsing of malformed JPEG2000 files. The function CGImageReadGetBytesAtOffset can utilize miscalculated values during a memmove operation that will result in an exploitable heap corruption allowing attackers to execute arbitrary code under the context of the current user. • http://lists.apple.com/archives/security-announce/2010//Mar/msg00001.html http://support.apple.com/kb/HT4077 http://www.securityfocus.com/archive/1/510539/100/0/threaded http://www.zerodayinitiative.com/advisories/ZDI-10-058 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
