🔗 CVE IDs covered (1)
📋 Description
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.
