The version of Microsoft Office installed on the remote Mac OS X host is affected by multiple memory corruption issues due to improper handling of objects in memory. A remote attacker can exploit these issues by convincing a user to open a specially crafted file in an affected version of Office, resulting in the execution of arbitrary code in the context of the current user.
