The Microsoft Skype for Business or Microsoft Lync or Microsoft Live Meeting installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when     Windows Uniscribe improperly discloses the contents of     its memory. An attacker who successfully exploited the     vulnerability could obtain information to further     compromise the users system. There are multiple ways an     attacker could exploit the vulnerability, such as by     convincing a user to open a specially crafted document     or by convincing a user to visit an untrusted webpage.
    The update addresses the vulnerability by correcting how     Windows Uniscribe handles objects in memory.
    (CVE-2017-8695)

  - An information disclosure vulnerability exists in the     way that the Windows Graphics Device Interface (GDI)     handles objects in memory, allowing an attacker to     retrieve information from a targeted system. By itself,     the information disclosure does not allow arbitrary code     execution; however, it could allow arbitrary code to be     run if the attacker uses it in combination with another     vulnerability. To exploit this vulnerability, an     attacker would have to log on to an affected system and     run a specially crafted application. Note that where the     severity is indicated as Critical in the Affected     Products table, the Preview Pane is an attack vector for     this vulnerability. The security update addresses the     vulnerability by correcting how GDI handles memory     addresses. (CVE-2017-8676)

  - A remote code execution vulnerability exists due to the     way Windows Uniscribe handles objects in memory. An     attacker who successfully exploited this vulnerability     could take control of the affected system. An attacker     could then install programs; view, change, or delete     data; or create new accounts with full user rights.
    Users whose accounts are configured to have fewer user     rights on the system could be less impacted than users     who operate with administrative user rights. There are     multiple ways an attacker could exploit this     vulnerability: In a web-based attack scenario, an     attacker could host a specially crafted website designed     to exploit this vulnerability and then convince a user     to view the website. An attacker would have no way to     force users to view the attacker-controlled content.
    Instead, an attacker would have to convince users to     take action, typically by getting them to click a link     in an email or instant message that takes users to the     attacker's website, or by opening an attachment sent     through email. In a file-sharing attack scenario, an     attacker could provide a specially crafted document file     designed to exploit this vulnerability and then convince     a user to open the document file.The security update     addresses the vulnerability by correcting how Windows     Uniscribe handles objects in memory.
