| <p>A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. To exploit the vulnerability, an attacker could run a specially crafted application on a guest operating system that could cause the Hyper-V host operating system to execute arbitrary code.</p>
<p>An attacker who successfully exploited the vulnerability could execute arbitrary code on the host operating system.</p>
<p>The security update addresses the vulnerability by correcting how Hyper-V validates guest operating system user input.</p>
|
| <p>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.</p>
<p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application to take control of an affected system.</p>
<p>The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.</p>
|
| <p>An information disclosure vulnerability exists when the Windows KernelStream improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.</p>
<p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.</p>
<p>The update addresses the vulnerability by correcting how the Windows KernelStream handles objects in memory.</p>
|
| <p>An elevation of privilege vulnerability exists in the way that the Windows Network Connections Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.</p>
<p>To exploit the vulnerability, a locally authenticated attacker could run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the Windows Network Connections Service properly handles objects in memory.</p>
|
| <p>An elevation of privilege vulnerability exists when the Windows Storage VSP Driver improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.</p>
<p>To exploit the vulnerability, an attacker would first need code execution on a victim system. An attacker could then run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the Windows Storage VSP Driver properly handles file operations.</p>
|
| <p>An information disclosure vulnerability exists when a Windows Projected Filesystem improperly handles file redirections. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user's system</p>
<p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability.</p>
<p>The security update addresses the vulnerability by correcting how Windows Projected Filesystem handle file redirections.</p>
|
| <p>An elevation of privilege vulnerability exists when Microsoft Windows improperly handles reparse points. An attacker who successfully exploited this vulnerability could overwrite or delete a targeted file that would normally require elevated permissions.</p>
<p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and overwrite or delete files.</p>
<p>The security update addresses the vulnerability by correcting how Windows handles reparse points.</p>
|
| <p>An elevation of privilege vulnerability exists when the Windows Application Compatibility Client Library improperly handles registry operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.</p>
<p>To exploit the vulnerability, an attacker would first need code execution on a victim system. An attacker could then run a specially crafted application.</p>
<p>The security update addresses the vulnerability by ensuring the Windows Application Compatibility Client Library properly handles registry operations.</p>
|
| <p>A denial of service vulnerability exists in Windows Remote Desktop Service when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the Remote Desktop Service on the target system to stop responding.</p>
<p>To exploit this vulnerability, an attacker would need to run a specially crafted application against a server which provides Remote Desktop Service.</p>
<p>The update addresses the vulnerability by correcting how Remote Desktop Service handles connection requests.</p>

| An issue was discovered in Zalo.exe in VNG Zalo Desktop 19.8.1.0. An attacker can run arbitrary commands on a remote Windows machine running the Zalo client by sending the user of the device a crafted file. |
| Insufficient policy enforcement in networking in Google Chrome prior to 87.0.4280.66 allowed a remote attacker to potentially bypass firewall controls via a crafted HTML page. |
| Heap buffer overflow in UI in Google Chrome on Windows prior to 86.0.4240.183 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. |
| Insufficient policy enforcement in downloads in Google Chrome on Windows prior to 86.0.4240.75 allowed a remote attacker who convinced the user to open files to execute arbitrary code via a crafted HTML page. |
| In Python 3.8.4, sys.path restrictions specified in a python38._pth file are ignored, allowing code to be loaded from arbitrary locations. The <executable-name>._pth file (e.g., the python._pth file) is not affected. |
| Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions. |
| GRUB2 contains a race condition in grub_script_function_create() leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2 version 2.04 and prior versions. |
| GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. |
| Firefox could be made to load attacker-supplied DLL files from the installation directory. This required an attacker that is already capable of placing files in the installation directory. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. |
| This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PhantomPDF 9.7.2.29539. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the NodeProperties::InferReceiverMapsUnsafe method. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-10950. |
