Two vulnerabilities have been identified in Microsoft Word, which could be exploited by attackers to take complete control of an affected system.
The first issue is due to a lack of validation of certain properties in modified documents, which could be exploited by attackers to cause a vulnerable application to not prompt the user with a macro security warning when executing macros present in a malicious document.
The second vulnerability is due to a memory corruption error when handling a document containing a malformed drawing object, which could be exploited by attackers to execute arbitrary commands by tricking a user into opening a specially crafted Word document.
