-- CVE ID:
CVE-2008-3635

-- Affected Vendors:
Apple

-- Affected Products:
Apple Quicktime

-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on

The specific flaw exists within the parsing of QuickTime files that
utilize the Indeo video codec. A lack of proper bounds checking within
QuickTimeInternetExtras.qtx can result in a stack based buffer overflow
leading to arbitrary code execution under the context of the currently
logged in user.
