A Security Update has been released for Outlook 2010. It resolves the following vulnerability;
- CVE-2019-1084: Microsoft Exchange Information Disclosure Vulnerability (All)
An information disclosure vulnerability exists when Exchange allows creation of entities with Display Names having non-printable characters. An authenticated attacker could exploit this vulnerability by creating entities with invalid display names, which, when added to conversations, remain invisible. 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.
Note: This update can be installed via Microsoft Update and updates Outlook to version 14.0.7235.5000.
