A Security Update has been released for Outlook 2013. 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.
Additionally, the holiday file (Outlook.HOL) has been updated to extend the date range to the year 2026 for many events. To update your holidays, you’ll have to remove the current ones from your Calendar and re-import them. For more info see; Holiday updates for the Outlook Calendar.
