(0Day) Apple QuickTime 'mvhd' Atom Heap Memory Corruption Remote Code Execution Vulnerability

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 ‘mvhd’ atom. By providing a malformed version and flags, an attacker is able to create controllable memory corruption, and trigger an arbitrary write operation. By exploiting this, an attacker could execute code in the context of the current user.
