Heap-based buffer overflow in Apple QuickTime before 7.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted STSS atoms in a QuickTime movie file. Desbordamiento de buffer basado en memoria dinámica en Apple QuickTime en versiones anteriores a 7.7 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (caída de la aplicación) a través de atoms STTS modificados en un archivo de película QuickTime. 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 way Quicktime handles invalid values in the Sync Sample Atom. Due to a signed compare instead of an unsigned compare it is possible to corrupt the Sample Atom Table. • http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.apple.com/archives/security-announce/2011//Aug/msg00000.html http://support.apple.com/kb/HT5002 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A15885 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Heap-based buffer overflow in Apple QuickTime before 7.7 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via crafted STSZ atoms in a QuickTime movie file. Desbordamiento de buffer basado en memoria dinámica en Apple QuickTime en versiones anteriores a 7.7 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (caída de la aplicación) a través de atoms STSZ en un archivo de película QuickTime. 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 way Quicktime handles corrupt Sample Size atoms. When the value for 'Number of Entries' in this atom differs from the 'Number of Entries' in the Time-To-Sample atom, Quicktime will fill the Atom Sample Table with uninitialized data read from memory. • http://lists.apple.com/archives/Security-announce/2011//Oct/msg00003.html http://lists.apple.com/archives/security-announce/2011//Aug/msg00000.html http://support.apple.com/kb/HT5002 https://oval.cisecurity.org/repository/search/definition/oval%3Aorg.mitre.oval%3Adef%3A16143 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

WebKit, as used in Apple Safari before 5.0.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2011-07-20-1. WebKit, como se usa en Safari de Apple anterior a v5.0.6, permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y caída de la aplicación) a través de un sitio web manipulado, una vulnerabilidad diferente a otros CVEs WebKit listados en APPLE-SA-2011-07-20-1. • http://lists.apple.com/archives/Security-announce/2011//Oct/msg00000.html http://lists.apple.com/archives/Security-announce/2011//Oct/msg00001.html http://lists.apple.com/archives/security-announce/2011//Jul/msg00002.html http://support.apple.com/kb/HT4808 http://support.apple.com/kb/HT4981 http://support.apple.com/kb/HT4999 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
