CVE-2010-3802

Error de presencia de signo (signedness) de entero en Apple QuickTime anterior v7.6.9 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 atom panorama manipulado en un fichero QuickTime Virtual Reality (QTVR)

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 a user must be coerced into visiting a malicious page or opening a malicious file.
The specific flaw exists within Apple's support for Panoramic Images and occurs due to the application trusting a particular field for calculation of an offset. Due to the field being treated as a signed integer, the calculated offset can result in a pointer outside the bounds of the expected buffer. Upon usage of this out-of-bounds pointer, the application will write proceed to write image data to the invalid location. Successful exploitation can lead to code execution under the context of the application.
