-- Vulnerability Details:
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 QuickTimeAuthoring.qtx during the
parsing of DELTA_FLI chunks stored within a malformed .fli file. The
applications trusts a user-supplied length for decompression which can
be modified to copy more data than necessary leading to a buffer
overflow. Successful exploitation can lead to code execution under the
context of the current user.
