-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle Java. 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 the way Java parses soundbank files.
When a soundbank file contains compressed data it is first decompressed
and then Java will parse the decompressed data. Java will read the
'channels' and 'frames' properties from the decompressed data and uses
those to calculate a buffer size to store data. An integer wrap can
occur during this calculation resulting in the creation of a buffer that
is too small to hold all the data. This can result in remote code
execution under the context of the current user.

-- Vendor Response:
Oracle has issued an update to correct this vulnerability. More
