4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Adobe Camera Raw
Plug-in, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to an integer overflow error in the
"Camera Raw.8bi" plug-in when allocating memory during TIFF image
processing and can be exploited to cause a heap-based buffer overflow
via specially crafted image dimensions.

Successful exploitation may allow execution of arbitrary code,
but requires tricking a user into opening or previewing a malicious
file.

======================================================================
5) Solution 

Update the plug-in to version 7.3 via the application's update
mechanism.
