An attacker     who successfully exploited this vulnerability could     potentially read data that was not intended to be     disclosed. Note that this vulnerability would not allow     an attacker to execute code or to elevate their user     rights directly, but it could be used to obtain     information that could be used to try to further     compromise the affected system.  (CVE-2020-0615,     CVE-2020-0639)

  - An elevation of privilege vulnerability exists in     Windows when the Win32k component fails to properly     handle objects in memory. An attacker who successfully     exploited this vulnerability could run arbitrary code in     kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts     with full user rights.  (CVE-2020-0642)

  - A remote code execution vulnerability exists in .NET     software when the software fails to check the source     markup of a file. An attacker who successfully exploited     the vulnerability could run arbitrary code in the     context of the current user. If the current user is     logged on with administrative user rights, an attacker     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.
    (CVE-2020-0605, CVE-2020-0606)

  - A denial of service vulnerability exists when Microsoft     Hyper-V Virtual PCI on a host server fails to properly     validate input from a privileged user on a guest     operating system.  (CVE-2020-0617)

  - An elevation of privilege vulnerability exists in     Microsoft Windows when Windows fails to properly handle     certain symbolic links. An attacker who successfully     exploited this vulnerability could potentially set     certain items to run at a higher level and thereby     elevate permissions.  (CVE-2020-0635)

  - An information disclosure vulnerability exists in the     way that the Windows Graphics Device Interface Plus     (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.  (CVE-2020-0643)

  - A remote code execution vulnerability exists when     Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way     that an attacker could execute arbitrary code in the     context of the current user. An attacker who     successfully exploited the vulnerability could gain the     same user rights as the current user.  (CVE-2020-0640)

  - An information disclosure vulnerability exists when the     Microsoft Windows Graphics Component improperly handles     objects in memory. An attacker who successfully     exploited the vulnerability could obtain information to     further compromise the users system.  (CVE-2020-0622)

  - An information disclosure vulnerability exists when the     win32k component improperly provides kernel information.
    An attacker who successfully exploited the vulnerability     could obtain information to further compromise the users     system.  (CVE-2020-0608)

  - An elevation of privilege vulnerability exists when     Microsoft Cryptographic Services improperly handles     files. An attacker could exploit the vulnerability to     overwrite or modify a protected file leading to a     privilege escalation.  (CVE-2020-0620)

  - An elevation of privilege vulnerability exists when the     Windows Common Log File System (CLFS) driver improperly     handles objects in memory. An attacker who successfully     exploited this vulnerability could run processes in an     elevated context.  (CVE-2020-0634)

  - An elevation of privilege vulnerability exists in     Windows Media Service that allows file creation in     arbitrary locations.  (CVE-2020-0641)

  - An information disclosure vulnerability exists in the     way that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could obtain information that could be     useful for further exploitation.  (CVE-2020-0607)

  - A remote code execution vulnerability exists when the     Microsoft .NET Framework fails to validate input     properly. An attacker who successfully exploited this     vulnerability could take control of an 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.
    (CVE-2020-0646)

  - A remote code execution vulnerability exists in the     Windows Remote Desktop Client when a user connects to a     malicious server. An attacker who successfully exploited     this vulnerability could execute arbitrary code on the     computer of the connecting client. An attacker could     then install programs; view, change, or delete data; or     create new accounts with full user rights.
    (CVE-2020-0611)

  - An elevation of privilege vulnerability exists when     Microsoft Windows implements predictable memory section     names. An attacker who successfully exploited this     vulnerability could run arbitrary code as system. An     attacker could then install programs; view, change, or     delete data; or create new accounts with full user     rights.  (CVE-2020-0644)

  - A spoofing vulnerability exists in the way Windows     CryptoAPI (Crypt32.dll) validates Elliptic Curve     Cryptography (ECC) certificates. An attacker could     exploit the vulnerability by using a spoofed code-     signing certificate to sign a malicious executable,     making it appear the file was from a trusted, legitimate     source. The user would have no way of knowing the file     was malicious, because the digital signature would     appear to be from a trusted provider. A successful     exploit could also allow the attacker to conduct man-in-     the-middle attacks and decrypt confidential information     on user connections to the affected software. The     security update addresses the vulnerability by ensuring     that Windows CryptoAPI completely validates ECC     certificates. (CVE-2020-0601)

An attacker who successfully exploited     this vulnerability could execute arbitrary code on the     computer of the connecting client. An attacker could     then install programs; view, change, or delete data; or     create new accounts with full user rights.
    (CVE-2020-0611)

  - An elevation of privilege vulnerability exists when     Microsoft Windows implements predictable memory section     names. An attacker who successfully exploited this     vulnerability could run arbitrary code as system. An     attacker could then install programs; view, change, or     delete data; or create new accounts with full user     rights.  (CVE-2020-0644)

  - A spoofing vulnerability exists in the way Windows     CryptoAPI (Crypt32.dll) validates Elliptic Curve     Cryptography (ECC) certificates. An attacker could     exploit the vulnerability by using a spoofed code-     signing certificate to sign a malicious executable,     making it appear the file was from a trusted, legitimate     source. The user would have no way of knowing the file     was malicious, because the digital signature would     appear to be from a trusted provider. A successful     exploit could also allow the attacker to conduct man-in-     the-middle attacks and decrypt confidential information     on user connections to the affected software. The     security update addresses the vulnerability by ensuring     that Windows CryptoAPI completely validates ECC     certificates. (CVE-2020-0601)
