CVE-2011-0247 describes multiple stack-based buffer overflows in Apple QuickTime for Windows, affecting versions prior to 7.7. This critical vulnerability allows remote attackers to execute arbitrary code or cause a denial of service by tricking users into opening a specially crafted H.264 movie. With a CVSS score of 9.3, it presents a high risk due to its network-based attack vector and complete compromise potential for confidentiality, integrity, and availability.
