Code Execution:

Arbitrary code execution under the context of the logged in user
Internet Explorer remote code execution vulnerabilities have very high impacts since the source of the malicious payload can be any site on the Internet. An even more critical problem is generated when clients are administrators on their local hosts, which would run the malicious payload with Administrator credentials.

No mitigation strategies exist for Internet Explorer.
