Apple Quicktime < 7.7.4
描述：
--------------------------------------------------------------------------------
BUGTRAQ ID: 60097
CVE（CAN） ID: CVE-2013-1017QuickTime是由苹果电脑所开发的一种多媒体架构，能够处理许多的数字视频、媒体段落、音效、文字、动画、音乐格式，以及交互式全景影像的数项类型。Windows 7, Vista, XP平台上的QuickTime 7.7.4没有正确处理Alis记录内的如"rdrf"或"dref"的某些原子的数据长度，特制的.mov文件即可触发缓冲区溢出，造成任意代码执行。<*来源：Tom Gallagher

"Name" => "Apple Quicktime 7 Invalid Atom Length Buffer Overflow",
"Description" => %q{
This module exploits a vulnerability found in Apple Quicktime. The flaw is
triggered when Quicktime fails to properly handle the data length for certain
atoms such as "rdrf" or "dref" in the Alis record, which may result a buffer
overflow by loading a specially crafted .mov file, and allows arbitrary
code execution under the context of the user.
