Summary
An information disclosure vulnerability exists when Exchange allows creation of entities with Display Names having non-printable characters.

This security update addresses the issue by validating display names upon creation in Microsoft Exchange, and by rendering invalid display names correctly in Microsoft Outlook clients., aka 'Microsoft Exchange Information Disclosure Vulnerability'.
