Vulnerabilities

A remote code execution vulnerability exists in the way that Microsoft Windows Codecs Library handles objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code.<br /> Exploitation of the vulnerability requires that a program process a specially crafted image file.<br /> The update addresses the vulnerability by correcting how Microsoft Windows Codecs Library handles objects in memory.

A remote code execution vulnerability exists in Visual Studio Code when a user is tricked into opening a malicious &amp;#39;package.json&amp;#39; 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.<br /> To exploit this vulnerability, an attacker would need to convince a target to clone a repository and open it in Visual Studio Code. Attacker-specified code would execute when the target opens the malicious &amp;#39;package.json&amp;#39; file.<br /> The update address the vulnerability by modifying the way Visual Studio Code handles JSON files.

An elevation of privilege vulnerability exists when Windows Hyper-V on a host server fails to properly handle objects in memory. An attacker who successfully exploited these vulnerabilities could gain elevated privileges on a target operating system.<br /> This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.<br /> The update addresses the vulnerabilities by correcting how Windows Hyper-V handles objects in memory.

A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system.<br /> To exploit the vulnerability, a user would have to open a specially crafted file.<br /> The security update addresses the vulnerability by correcting how Microsoft Graphics Components handle objects in memory.

A denial of service vulnerability exists when Microsoft Hyper-V on a host server fails to properly validate specific malicious data from a user on a guest operating system.<br /> To exploit the vulnerability, an attacker who already has a privileged account on a guest operating system, running as a virtual machine, could run a specially crafted application.<br /> The security update addresses the vulnerability by resolving the conditions where Hyper-V would fail to handle these requests.

An information disclosure vulnerability exists when Microsoft SharePoint Server fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.<br /> To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.<br /> The security update addresses the vulnerability by correcting how Microsoft SharePoint Server handles objects in memory.

A remote code execution vulnerability exists in Microsoft Office software when the software fails to properly handle 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.<br /> Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of Microsoft Office. 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.<br /> The security update addresses the vulnerability by correcting how Microsoft Office handles objects in memory.

An elevation of privilege vulnerability exists in the way that Microsoft Office Click-to-Run (C2R) AppVLP handles certain files. An attacker who successfully exploited the vulnerability could elevate privileges.<br /> To exploit this vulnerability, an attacker would need to convince a user to open a specially crafted file.<br /> The security update addresses the vulnerability by correcting how Microsoft Office Click-to-Run (C2R) components handle these files.

A cross site scripting vulnerability exists when Microsoft Dynamics 365 (on-premises) does not properly sanitize a specially crafted web request to an affected Dynamics server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected Dynamics server.<br /> The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run script in the security context of the current authenticated user. These attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim&amp;#39;s identity to take actions within Dynamics Server on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user.<br /> The security update addresses the vulnerability by helping to ensure that Dynamics Server properly sanitizes web requests.

A remote code execution vulnerability exists when the Microsoft Office Access Connectivity Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system.<br /> An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file.<br /> The update addresses the vulnerability by correcting the way the Microsoft Office Access Connectivity Engine handles objects in memory.

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.<br /> 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.<br /> The security update addresses the vulnerability by correcting how the Windows Camera Codec Pack handles objects in memory.
