  "description": "\u003Cp\u003EAn information disclosure vulnerability exists when Microsoft Outlook fails to properly validate authentication requests.\u003C/p\u003E\n\u003Cp\u003ETo exploit the vulnerability an attacker would have to trick a user into browsing to a malicious website or to an SMB or UNC path destination. Alternatively the attacker could convince a user to load a malicious document that initiates an NTLM validation request without the consent of the user. An attacker who successfully tricked a user into disclosing the user\u0027s NTLM hash could attempt a brute-force attack to disclose the corresponding hash password.\u003C/p\u003E\n\u003Cp\u003EThe security update addresses the vulnerability by correcting how Outlook validates authentication requests.\u003C/p\u003E",
