-- CVE ID:
CVE-2010-0062

-- 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 quicktime.qts when parsing sample data
from a malformed .3g2 file that is utilizing the h.263 codec. While
parsing data to render the video stream, the application will
miscalculate the length of a buffer. Later when decompressing data to
the heap chunk, the application will overflow the under allocated buffer
leading to code execution under the context of the currently logged in
user.

-- Vendor Response:
Apple has issued an update to correct this vulnerability. More
details can be found at:
