November 9, 2010

-- CVE ID:
CVE-2010-0515

-- CVSS:
9, (AV:N/AC:L/Au:N/C:P/I:P/A:C)

-- Affected Vendors:
Apple

-- Affected Products:
Apple Quicktime

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Apple QuickTime Player. 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 during the parsing of samples from a malformed
MOV file utilizing the H.264 codec. While parsing data to render the
stream, the application will miscalculate a length that is used to
initialize a heap chunk that was allocated in a header. If the length is
larger than the size of the chunk allocated, then a memory corruption
will occur which can lead to code execution under the context of the
application.

-- Vendor Response:
Apple states:
Fixed in QuickTime 7.6.6
