CVE-2020-1189, CVE-2020-1190, CVE-2020-1191)
- An elevation of privilege vulnerability exists in the
way that the Windows Kernel handles objects in memory.
An attacker who successfully exploited the vulnerability
could execute code with elevated permissions.
(CVE-2020-1087)
- An elevation of privilege vulnerability exists when
Windows improperly handles errors tied to Remote Access
Common Dialog. An attacker who successfully exploited
the vulnerability could run arbitrary code with elevated
privileges. (CVE-2020-1071)
- A remote code execution vulnerability exists in the way
that the Chakra scripting engine handles objects in
memory in Microsoft Edge (HTML-based). 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-2020-1037)
- An elevation of privilege vulnerability exists when the
Windows kernel 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-2020-1114)
- 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-2020-1154)
- An elevation of privilege vulnerability exists in
Windows Media Service that allows file creation in
arbitrary locations. (CVE-2020-1068)
- An information disclosure vulnerability exists when the
Windows Client Server Run-Time Subsystem (CSRSS) fails
to properly handle objects in memory. An attacker who
successfully exploited the vulnerability could obtain
information to further compromise the users system.
(CVE-2020-1116)
- A remote code execution vulnerability exists in the way
that the VBScript engine handles 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-2020-1035, CVE-2020-1058,
