-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of the Adobe Shockwave 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 within the parsing of the rcsL RIFF chunk
within Director files. When handling specific structures within this
chunk, the process trusts an offset and uses it to calculate a pointer
value. By modifying this element an attacker can force the application
to corrupt memory at a controlled location. This can be leveraged by an
attacker to execute arbitrary code under the context of the user running
the browser.

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