-- 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 in the handling of STSZ atoms within the
function CallComponentFunctionWithStorage(). When an entry in the
sample_size_table is too large, a memory corruption occurs which can be
further leveraged to execute arbitrary code under the context of the
current user.
