| CVE-2020-15707 | 8 Canonical, Debian, Gnu and 5 more | 15 Ubuntu Linux, Debian Linux, Grub2 and 12 more | 2024-11-21 | 4.4 MEDIUM | 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 | 14 Ubuntu Linux, Debian Linux, Grub2 and 11 more | 2024-11-21 | 4.4 MEDIUM | 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 | 14 Ubuntu Linux, Debian Linux, Grub2 and 11 more | 2024-11-21 | 4.4 MEDIUM | 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. | |||||
| CVE-2020-0999 | 1 Microsoft | 8 Windows 10, Windows 7, Windows 8.1 and 5 more | 2024-11-21 | 9.3 HIGH | 7.8 HIGH |
| A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory, aka 'Jet Database Engine Remote Code Execution Vulnerability'. This CVE ID is unique from CVE-2020-0889, CVE-2020-0953, CVE-2020-0959, CVE-2020-0960, CVE-2020-0988, CVE-2020-0992, CVE-2020-0994, CVE-2020-0995, CVE-2020-1008. | |||||

| CVE-2020-0997 | 1 Microsoft | 3 Windows 10, Windows Server 2016, Windows Server 2019 | 2024-11-21 | 9.3 HIGH | 7.8 HIGH |
| <p>A remote code execution vulnerability exists when the Windows Camera Codec Pack improperly handles objects in memory. 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. 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.</p> <p>Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of the Windows Camera Codec Pack. In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.</p> <p>The security update addresses the vulnerability by correcting how the Windows Camera Codec Pack handles objects in memory.</p> | |||||
