WebKit, as used in Apple iTunes before 10.2 on Windows and Apple iOS, does not properly implement the .sort function for JavaScript arrays, which allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors related to iTunes Store browsing, a different vulnerability than other CVEs listed in APPLE-SA-2011-03-02-1.
