Description
A remote code execution issue exists in Microsoft PowerPoint software due to its failure to properly handle objects in memory. This could allow an attacker to run arbitrary code in the context of the current user by using a specially crafted file. If the current user has administrative user rights, the attacker could take control of the affected system, install programs, view, change, or delete data, or create new accounts with full user rights. Users with fewer user rights on the system could be less impacted than those operating with administrative user rights.
