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 kernel image properly handles objects in memory.</p>
CVE-2020-16891 1 Microsoft 18 Windows 10, Windows 10 1507, Windows 10 1607 and 15 more 2024-11-21 8.8 High
<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>
CVE-2020-16889 1 Microsoft 19 Windows 10, Windows 10 1507, Windows 10 1607 and 16 more 2024-11-21 5.5 Medium
<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.

CVE-2020-15707 8 Canonical, Debian, Gnu and 5 more 19 Ubuntu Linux, Debian Linux, Grub2 and 16 more 2024-11-21 5.7 Medium
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.
CVE-2020-15706 7 Canonical, Debian, Gnu and 4 more 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more 2024-11-21 6.4 Medium
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.
CVE-2020-15705 7 Canonical, Debian, Gnu and 4 more 18 Ubuntu Linux, Debian Linux, Grub2 and 15 more 2024-11-21 6.4 Medium
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.

<p>An elevation of privilege vulnerability exists when the Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context.</p> <p>In a local attack scenario, an attacker could exploit this vulnerability by running a specially crafted application to take control over the affected system.</p> <p>The update addresses the vulnerability by correcting the way in which the Microsoft Graphics Component handles objects in memory and preventing unintended elevation from user mode.</p>
