Hi, Apple Quicktime <= 7.1 is prone to a heap overflow vulnerability. This flaw could lead to a remote code execution,if an attacker tricks the victim to visit a malicious webpage with a specially crafted .fli animation embedded. The flaw is located within the "COLOR_64 chunk" Quicktime parser. Since proper checking is not performed, a large amount of heap can be overwritten with controlled values.
