A malformed QuickTime chapter track can set stsz's default sample size to a value larger than the available sample data. MP4::File::qtChapters() passes that value through QtChapterList::read() to readTextSample(), allowing a small file to cause gigabytes of allocations and terminate the application. Check each resolved sample against the file end and the next sample offset before reading it. Samples that do not fit are rejected without allocating the attacker-controlled size.
