| Business Impact: |
Compromise of machines using affected versions of the oleaut32 library may lead to exposure of confidential information, loss of productivity, and further compromise. An attacker may need to entice a user to visit a web page, or open a specially-crafted file to trigger this vulnerability. Successful exploitation grants an attacker system-level privileges. |
