CVE-1999-1164

Summary

CVE-1999-1164 is a denial-of-service vulnerability affecting Microsoft Outlook. An attacker can cause Outlook to hang by sending multiple emails with identical X-UIDL headers. This issue arises due to Outlook's mishandling of these headers, resulting in a resource consumption issue that ultimately leads to a denial-of-service condition. Microsoft Outlook clients prior to a specific patch release are susceptible to this issue. To mitigate the risk, users are advised to apply the relevant security updates as soon as possible.
