Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on 
vulnerable installations of Bitdefender Internet Security. 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 pdf.xmd. The issue results from the lack of 
proper validation of user-supplied data, which can result in an integer 
overflow before allocating a buffer. An attacker can leverage this 
vulnerability to execute code under the context of SYSTEM.
