Detailed Description

Business Impact:

Compromise of machines using affected versions of Adobe Reader and Acrobat may lead to exposure of confidential information, loss of productivity, and further network compromise. Remote code execution could be achieved by enticing a user to visit a web page or to open a specially crafted PDF file. A successful exploitation attempt results in code execution with privileges of the current user. The Protected Mode sandbox feature first introduced in Adobe Reader X in Windows should limit the impact of successful attacks, however, exploits seen in the wild were found using a separate vulnerability to bypass this security feature.
