Detailed Description |
| Business Impact: |
Compromise of machines using affected versions of Firefox or other Mozilla-based applications may lead to exposure of confidential information, loss of productivity, and further compromise. An attacker must cause the victim user to browse to a malicious web page, click a link in a malicious email, or similar operation in order to perform a successful attack. Successful exploitation grants an attacker the privileges of the victim. |
